IntroductionAs component leader for engine generator applications, Eaton pro-vides circuit breakers for original equipment manufacturers (OEMs) who produce engine generator sets, paralleling gear and transfer switchgear, as well as system integrators who provide engine gen-erator packages. Typical applications include diesel generator sets and portable or temporary power units providing a range of power ratings. Engine generator applications rely on circuit breakers to pro-vide circuit protection for valuable assets and to keep critical facilities and processes running.Eaton circuit protection solutions enable:• Reliable operation • Robust performance •Enhanced safety1.1 General InformationThe L -frame Series C circuit breaker (see Figure 1) type LG is a 600 Vac maximum rated device with an electronic 310+ RMS trip unit rated 600 A maximum for continuous current. Molded case circuit breakers are listed in accordance with Underwriters Laboratories, Inc. Standard UL 489.This instruction leaflet (IL) gives procedures for installation and field testing of L -frame Series C circuit breakers.3Instruction Leaflet IL012062ENEffective July 2015Installation Instruction for Eaton LG 310+ Engine Generator Circuit BreakersEATON 2. InstallationThe installation procedure consists of inspecting the circuit breaker and, as applicable, installing accessories, and terminals; mounting the circuit breaker; connecting the line and load conductors; torqu-ing terminals; and attaching terminal shields. Circuit breaker frames with trip units, accessories, mounting hardware, and unmounted terminals may be supplied in separate packages. To install the circuit breaker, perform the following steps.otee:N Internal accessory installation in any type of circuit breaker should be done before the circuit breaker is mounted and connected. Refer to individual accessory instruction leaflets for specific installation instructions on field installable accessories.Step 1. Compare name plate data with existing equipment ratings and system requirements to make sure that the circuit breaker is suitable for the intended installation. Prior to mounting, confirm that the circuit breaker has not been damaged during transit or initial handling.Step 2. To install any internal accessories, remove installed cover screws and cover.otee:N The circuit breaker handle must be in the tripped or OFF position to remove the cover. Instructions for installing the trip unit and accessories are supplied with the devices.Step 3. If not already installed, mount accessories (if required) in circuit breaker frame.otee:N When required to be removed or replaced, stationary interphase bar-riers can only be installed or removed with circuit breaker in the tripped or open position.Step 4. After any internal accessories are installed, and with the cir-cuit breaker in the tripped position, make sure that stationary inter-phase barriers are properly installed in base. Install cover and secure with pan-head screws. Eight screws are used for two and three pole circuit breakers. Torque to 20-22 Ib-in (2.26-2.49 N.m.).Step 5. If not already installed, mount wire connecting terminals as shown in Figure 2. Secure the terminals to the circuit breaker using two pan-head slotted screws and lock washers. Torque to 6 to 8 Ib-ft (8.14 to 10.85 N·m). With the circuit breaker mounted and before the conductors are installed and conductor clamping screws inserted, the terminal mounting screws may be checked for correct torque.WARNINGTHE VOLTAGES IN ENERGIZED EQUIPMENT CAN CAUSE DEATH OR SEVERE PERSONAL INJURY. BEFORE MOUNTING THE CIRCUIT BREAKER IN AN ELECTRICAL SYSTEM, MAKE SURE THERE IS NO VOLTAGE PRESENT WHERE WORK IS TO BE PERFORMED. SPECIAL ATTENTION SHOULD BE PAID TO REVERSE FEED APPLICATIONS TO ENSURE NO VOLTAGE IS PRESENT.Figure 2.LDorPan -Head Screws Pan -Headand Lockwashers (Installed beforeT erminal Installationotee:N Depending on the equipment configuration, the circuit breaker can be mounted using different styles of hardware. The following steps describe how to mount the circuit breaker using standard hardware. When special hard-ware is needed (for example, with the motor operator), the instruction leaflet describing the accessory also describes the special mounting arrangements.Step 6. To mount the circuit breaker, perform the following steps:a. For individual surface mounting, drill mounting panel usingthe drilling plan shown in Figure 3. For panel board mounting, only load end support mounting holes are required. For dead front cover applications, cut out cover to correct escutcheon dimensions (see Figure 4).b.

Manual OperationWARNINGCONTACT WITH ENERGIZED EQUIPMENT CAN RESULT IN DEATH, SEVERE PERSONAL INJURY, OR SUBSTANTIAL PROPERTY DAMAGE. DO NOT ATTEMPT TO INSTALL OR PERFORM MAINTENANCE ON EQUIPMENT WHILE IT IS ENERGIZED. ALWAYS VERIFY THAT NO VOLTAGE IS PRESENT BEFORE PROCEEDING WITH THE TASK, AND ALWAYS FOLLOW GENERALLY ACCEPTED SAFETY PROCEDURES.otee:N When replacing an existing circuit breaker of the types listed, make sure the voltage, continuous current, and interrupting rating of the new circuit breaker are suitable.Manual operation of the circuit breaker is controlled by the circuit breaker handle and the PUSH-TO-TRIP button in the trip unit. The circuit breaker handle has three positions, two of which are shown on the cover with raised lettering to indicate ON and OFF .On the handle, ON, OFF , and trip are also shown by a color-coded strip for each circuit breaker handle position: red for ON, white for tripped, and green for OFF (see Figure 6).3.1 Circuit Breaker ResetAfter a trip operation, the circuit breaker is reset by moving the cir-cuit breaker handle to the Reset (extreme OFF) position.otee:N In the event of a thermal (overload) trip, the circuit breaker cannot be reset immediately. A circuit breaker with a DIGITRIP 310+ RMS trip unit simulates the thermal element of a thermal-magnetic type trip unit with an electronic “thermal memory“ that also requires up to five minutes to “cool” before it can be re-energized. No circuit breaker should be reclosed until the cause of trip is known and the situation rectified.3.2 PUSH-TO-TRIP ButtonThe PUSH-TO-TRIP button operates the circuit breaker tripping func-tion and may be used to periodically exercise the operating mecha-nism.Figure 6. Circuit Breaker Manual Controls.4. Inspection and Field TestingSeries C molded case circuit breakers are designed to provide years of almost maintenance-free operation. The following proceduredescribes how to do a limited amount of field inspection and testing of a circuit breaker.4.1 InspectionCircuit breakers in service should be inspected periodically. The inspection should include the following checks 1 through 8.WARNINGTHE VOLTAGES IN ENERGIZED EQUIPMENT CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. BEFORE INSPECTING THE CIRCUITBREAKER IN AN ELECTRICAL SYSTEM, MAKE SURE THE CIRCUIT BREAKER IS SWITCHED TO THE OFF POSITION AND THAT THERE IS NO VOLTAGE PRESENT WHERE WORK IS TO BE PERFORMED. PAY SPECIAL ATTENTION TO REVERSE FEED APPLICATIONS TO ENSURE NO VOLTAGE IS PRESENT.CAUTIONSOME COMMERCIAL CLEANING AGENTS WILL DAMAGE THENAMEPLATES OR MOLDED PARTS. MAKE SURE THAT CLEANING AGENTS OR SOLVENTS USED TO CLEAN THE CIRCUIT BREAKER ARE SUITABLE FOR THE JOB.Step 1. Remove dust, dirt, soot, grease, or moisture from the sur-face of the circuit breaker using a lint-free dry cloth, brush, or vacu-um cleaner. Do not blow debris into circuit breaker. If contamination is found, look for the source and eliminate the problem.Step 2. Switch circuit breaker to ON and OFF several times to be sure that the mechanical linkages operate freely and do not bind. If mechanical linkages do not operate freely, replace circuit breaker.Step 3. With the circuit breaker in the ON position, press the PUSH-TO-TRIP button to mechanically trip the circuit breaker. Trip, reset, and switch circuit breaker ON several times. If the mechanism does not reset each time the circuit breaker is tripped, replace the circuit breaker.Step 4. Check base, cover, operating handle, and handle barrier for cracks, chipping, and discoloration. Circuit breakers should be replaced if cracks or severe discoloration is found.Step 5. Check wire connecting terminals and other type bus bar connectors for looseness or signs of overheating. Overheating will show as discoloration, melting, or blistering of conductor insulation, or as pitting or melting of conductor surfaces due to arcing. If there is no evidence of overheating or looseness, do not disturb or tighten the connections. If there is evidence of overheating, terminations should be cleaned or replaced. Before re-energizing the circuit break-er, all terminations and cable should be refurbished to the originally installed condition.Step 6. Check circuit breaker mounting hardware, and tighten if nec-essary.Step 7. Exposure to certain types of chemicals can cause deteriora-tion of electrical connections. Check area where circuit breaker is installed for any safety hazards, including personal safety and fire hazards and take required precautionary actions.Step 8. The operation of circuit breakers with 310+ trip units can be field tested periodically using the Electronic test kit (See IL5721B13H05).4.2 Field T estingAny field testing should be done in accordance with applicable NEMA Standard.310+ Trip UnitInternational Symbols - ON - OFFHandle Position Indicator Color Red - ON White - TRIPGreen - OFF (Reset)Push-to-TripButton6EATON FILE = 6636C85_Rev-5DATE = 05/12/15S# 6636C85H32BAR CODE = 1066368532See Fig. 13Figure 8. Instantaneous T rip Settings.5. Features1. Remote Maintenance Mode (RMM) - OptionalAn option that allows a user to remotely lower the instantaneous pickup of the breaker to 2.5x the frame rating (In), and to bypass any programmed delays (tsd or tg). The purpose of the function is to reduce incident energy during a fault condition.For example, a 600A (In) LG breaker with the switch set to 2.5x would trip instantaneously when the current exceeded 1500 A. The RMM is enabled by applying 24VDC to the two wire cable that exits the left side of the breaker. The wires are color coded Y ellow (+24V) and Black (common ground) - (see Figure 9). A blue colored LED on the trip unit lights when the breaker is in RMM (see Figure 7).The lighted blue LED indicates that RMM is enabled. This setting corresponds to 2.5x of In. Turning the Isd switch on the trip unit has no effect on either the Maintenance Mode or the tsd\tg set-tings while the blue LED is lit.Also, a relay contact closure indicates that the RMM has been enabled. The blue and red wires are the C and NO contacts of this relay. The relay has a dual function: 1) enable RMM and 2) provide a contact closure indication that RMM is enabled.Both the yellow and black set of wires and the red and blue set of wires exit on the left side of the breaker.otee:N The RMM contacts are rated at 2A at 30 VDC and 0.5A at 125 VAC.no trip indicator when using the test port. In normal modes, the red LED indicates a high load alarm. For a high load alarm, it will blink ON-OFF if the continuous current is 105% of the Ir setting and is present for a duration over 38 seconds.3. High Load Alarm Relay - OptionalThis option will provide a SPST contact closure when the trip unit current equals or is greater than 105% of In for a period of 38 seconds. If the current drops below the 105% value, the contact will open. The yellow and green wires that exit the right side of the breaker are the common (C) and normally open (NO) of this relay (see Figure 10).Settings A = 500A B = 600A C = 800A D = 1000AE = 1250AF = 1500AG = 2000AH = 2500A7Instruction Leaflet IL012062ENEffective July 2015Installation Instruction for Eaton LG 310+ Engine Generator Circuit BreakersEATON Figure 10.

LSIG Short Delay and Ground Fault Time Settings.1 . Test Port - A test port is built into each trip unit to allow use of afunctional test kit . The test kit performs a test of the Long Delay, Short Delay and Ground Fault functions (Plug-In Test Kit Catalog #MTST230V) . Remove the test port cover prior to connecting to the test port .2 . Test/Alarm LED - A dual function, bi-color (red-amber) LED . It isused as an amber no trip indicator when using the test port . In normal modes, the red LED indicates a high load alarm . For a high load alarm, it will blink ON-OFF if the continuous current is 105% of the I r setting and is present for a duration over 38 sec-onds .3 . I r - Continuous current setting . In accordance with standardsrequirements, the trip unit initiates a trip of the circuit breaker within 2 hours for an overload of 135% and will trip as a function of l²t for higher currents . Continuous current values for each let-tered setting are indicated by the chart displayed on the left side of the trip unit label .4 . t r - The number of seconds required to trip @ 6x I r . For example,if I r = 250A, t r = 2 sec, and load current = 1500A, or 6x I r , then the breaker will trip in 2 seconds .5 . l sd - Setting in multiples of l r for short circuit conditions thatexceed the short delay pick-up setting, the trip unit initiates a trip after a predetermined delay .otee:N In addition to the short delay trip function, there is a fixed instan-taneous override for the 600A and 800A trip units . The override for the 600A is fixed at 5620A, the override for the 800A is fixed at 6800A . If a fault current exceeds these override values, the breaker will trip instanta-neously (in 20 milliseconds or less) .6 . I g - Ground fault pick-up setting . It is used on the LSIG and LSGstyles to set the ground fault pick-up as a percentage of I n (frame current) . For example, a 600A frame with an I g setting of 0 .4 will provide a ground fault pick-up at 240A .7 . t sd - for the LSI style, the short delay time is a flat responsedetermined by the tsd switch settings of INST 120ms, or 300ms . For the LS styles, the short delay time is an I²t function, with a delay of 67ms at a Isd setting of 6x .8 . t sd / t g - For the LSIG style, the short delay is a flat responsedetermined by the tsd/tg switch settings of INST 120ms or 300ms . This switch is a dual switch that also determines the ground fault time settings of INST , 120ms or 300ms . For exam-ple, if the t sd /t g switch is set at position J, then both short delay time and ground fault time are at INST flat . As another example, set the t sd /t g switch at position L; the short delay time is INST and the ground fault time is 300ms . The LSIG label (Figure 11) should be used in conjunction with the t sd /t g switch to set any one of nine possible combinations of short delay and ground fault times .9 . t g - For the LSG style, the short delay time is an I²t functionwhile the ground fault flat time is set by the t g switch .10 . Status LED - A green status light indicates the operational statusof the trip unit . If the load current exceeds approximately 20% of the maximum current rating (I n ) of the breaker, the status lightSection 3. Trip Unit Controls and FunctionsA .

Other features and options of the LES/MES 310+ trip units .1 . The High Load Alarm Relay option will provide a SPST contactclosure when the trip unit current equals or is greater than 105% of In for a period of 38 seconds . If the current drops below the 105% value, the contact will open . The yellow and green wires that exit the right side of the breaker are the common (C) and normally open (NO) of this relay (See Figure 12) .2 . The Ground Fault Alarm Only option operates in a similar fash-ion as the High Load Alarm . The SPST contact will close if the ground fault pick-up setting is exceeded and will open when below the ground fault pick-up setting . The yellow and green wires that exit the right side of the breaker are the common (C) and normally open (NO) of this relay (See Figure 12) .3 . The Ground Fault Relay option will provide a SPST contact clo-sure immediately before the breaker will trip on a ground fault over current detect . This closure is momentary (50ms) and the customer must provide the necessary external circuitry in order to latch this signal . The yellow and green wires that exit the right side of the breaker are the common (C) and normally open (NO) of this relay (See Figure 12) .otee:N The High Load Alarm Relay can be selected with LS, LSI LSG, and LSIG trip units . For the LSG and LSIG trip units, the High Load Alarm will function normally . However, if the breaker trips due to a ground fault con-dition, the relay will respond with a ground fault alarm as indicated above .The Ground Fault Alarm Only can be selected for LSG and LSIG trip units only . This selection has precedence over all other relay functions . When the Ground Fault Alarm Only is selected, the High Load Alarm Relay feature is not available .otee:N The contact ratings of the relay are: 2A at 30 VDC and 0 .5 A at 125 VAC .4 . The Zone Selective Interlock (ZSI) option provides a wired meth-od of coordinating Upstream and Downstream breakers . The coordinating signals are provided by the White\Red stripe (Z in ), White\Black stripe (Z out ), and Black (common ground) wires that exit the right side of the breaker . ZSI may be ordered on LSI and LSIG trip units .Zone Selective Interlocking is active for the short delay and the ground fault delay tripping functions . The LES/MES 310+ Trip Unit Zone Selective Interlocking feature is compatible with OPTIM and Digitrip Trip Units, including all other 310+ models on Series G: (RG, NG LG, JG) and Series C (FD and KD) breakers .Three wires exit the breaker with the following color code and function: White/Black Stripe=Zone Out, White/Red Stripe=Zone In, and Black=Common (See Figure 12) .A typical connection for a two breaker system is accomplished by connecting the Z out wire of the downstream breaker to the Z in of the upstream breaker . The common black wires of both break-ers must also be connected .If a high current fault is sensed from the load on the down-stream breaker, both breakers will sense the fault . However, the downstream breaker will send the interlock signal to the upstream breaker informing it not to trip . This delay allows the downstream breaker to clear the fault without the upstream breaker tripping .However, if for some reason the downstream breaker does not clear the fault in the set delay time, the upstream breaker will then clear the fault at or before its defined t sd or t g .Multiple breakers may be connected in a system to create a zone of protection . For faults outside the zone of protection, the trip unit of the circuit breaker nearest the fault sends an inter-locking signal (Z out ) to the trip unit of the up-stream circuit break-er . (Z in ) This interlocking signal restrains immediate tripping of the upstream circuit breaker until its programmed coordination time is reached . Thus zone selective interlocking applied correctly can reduce damage due to circuit or ground fault conditions . A table of the settings of the two breakers with the respective outcomes (Both Trip or Downstream (Dn) Trips) of the breakers is indicated below for the conditions mentioned in the table head-ing .UpstreamINST120ms 300ms D o w n s t r e a mINST Both Dn 43ms Dn 43ms 120ms Both Dn 52ms Dn 52ms 300msBothDn 43msDn 43msotee:N A single breaker with the Zone Selective Interlocking feature enabled will not trip at the programmed time settings, unless Self Interlocked . That is, the Z out wire should be connected to the Z in wire .5 . Remote Maintenance Mode (RMM) is an option that allows auser to remotely lower the instantaneous pickup of the breaker to 2 .5x the frame rating (I n ), and to bypass any programmed delays (t sd or t g ) . The purpose of the function is to to reduce inci-dent energy during a fault condition . For example, a 600A (I n ) LD breaker with the switch set to 2 .5x would trip instantaneously when the current exceeded 1500 A .The RMM is enabled by applying 24VDC to the two wire cable that exits the left side of the breaker . The wires are color coded Y ellow (+24V) and Black (common ground) - see Figure 14 . A blue colored LED on the trip unit lights when the breaker is in RMM (Figure 13) .The lighted blue LED indicates that RMM is enabled . This setting corresponds to 2 .5x of I n . Turning the I sd switch on the trip unit has no effect on either the Maintenance Mode or the t sd \t g set-tings while the blue LED is lit .Also, a relay contact closure indicates that the RMM has been enabled . The blue and red wires are the C and NO contacts of this relay . The relay has a dual function: 1) enable RMM and 2) provide a contact closure indication that RMM is enabled .Both the yellow and black set of wires and the red and blue set of wires exit on the left side of the breaker .otee:N The RMM contacts are rated at 2A at 30 VDC and 0 .5A at 125 VAC .7Instruction Leaflet IL012043ENEffective January 2016Instruction Leaflet for theLES/MES 310+ Electronic T rip Unit EATON Figure 12.

Neutral Current Sensor Informa-tion.Ground fault trip units are supplied from the factory with pigtail lead connections for a neutral current sensor (white and grey wires) . A neutral current sensor shown in Figure 14 is available . 310+ Ground Fault Trip Units detect ground fault currents through Residual Sensing . They are not designed to use source ground or zero sequence ground fault sensing methods . If the system neutral is grounded, but no phase to neutral loads are used, the neutral cur-rent sensor is not necessary . In that case, the white and grey leads on the trip should be cut off before installation . If the system neutral is grounded and phase to neutral loads are used, then the neutral current sensor must be used . It should be connected to the breaker according to Figure 15 It has the same turns ratio as the phase cur-rent sensors in the trip unit .NOTICETHE POLARITY OF THE SENSOR CONNECTIONS IS CRITICAL. ALWAYS OBSERVE THE POLARITY MARKINGS ON THE INSTALLATION DRAW-INGS. THE POLARITY MARKINGS ARE IDENTIFIED AS WHITE DOTS ON THE TRANSFORMERS. TO INSURE CORRECT GROUND FAULT EQUIPMENT PERFORMANCE, CONDUCT FIELD TESTS TO COMPLY WITH NATIONAL ELECTRIC CODE REQUIREMENTS UNDER ARTICLE 230-95-C.otee:N See wiring instructions below for special restrictions on accessory wir-ing for ground fault breakers . Then install the ground fault alarm and neutral current sensor connector printed circuit board as described previously .CAUTIONLEADS COULD BE DAMAGED IF IN CONTACT WITH MOVING PARTS. ACCESSORY WIRES SHOULD BE FORMED AND ROUTED TO CLEAR ALL MOVING PARTS.Leads to be routed:1 .2 leads (white and grey) for the neutral current sensor .2 . 2 leads (yellow and green) for the ground fault alarm relay It is not possible to have leads exiting the breaker on the opposite side . For rear exiting leads, thread the leads through the wiring troughs/tunnels in the side of the circuit breaker case . For side exiting leads, use the slots in the side of the case . Use the center trough or slot for the neutral current sensor leads (white and grey) and the trough or slot closest to the trip unit for the alarm leads (yel-low and green) .Any other leads to be brought out should then be threaded through the wiring trough closest to the trip unit .Section 5. 100% Rated LD and MDL Frame Circuit BreakersCLD, CHLD, CLDC, CMDL, and CHMDL circuit breakers are suitable for continuous operation at 100% of the frame rating if used with CU only 90° C insulated wire and AL9CU terminals in an enclosure which measures at least 24” high x 15” wide x 6” deep for the LD and 42" high x 18" wide x 7 .5" deep for the MDL .
