电子控制系统和其它敏感设备中的供电电压不稳定会导致整个生产线的瘫痪和生产设备的损坏以及长时间的停电。

TPM-300型微机无扰动切换控制装置为不间断供电提供了最佳的保证。

采用该装置后，可避免母线电压（残压）与备用电源电压差压过大合闸而对设备造成冲击；尽量缩短断电时间，可采用快速切换，如失去快速切换的机会，则装置自动转换为同相判别或残压判别的慢速切换，如果在一设定的时间结束之前无法进行切换，可执行长延时切换，作为三种切换的总后备。

通过快速自动切换到备用电源，TPM-300型保证了不间断的供电，并防止辅机的停机。

另外，人工启动快切的功能可大大简化设备的操作。

无扰动切换控制装置的任务是在供电线路断电的情况下，根据系统的状态以最快的速度把负荷切换到备用线路上，以保证负荷不断电连续运行。

考虑到应用领域的多样性，TPM-300根据断路器的状态自动识别是运行于双馈线的方式或是双馈线加母联的方式，为实现不间断的供电，应至少有两个同步且互相独立的供电电源同时装有快速切换控制装置。

特别适合两条线路具有同等地位的场合。

当线路故障引起供电中断时，快速切换控制装置的自动投入可避免停电时间过长。

即使一次简单的成功的切换，也可保证装置的持续工作，从而减少停电时间，节省了昂贵的重新启动的费用，即可补偿整个装置的投资。

由此，可大大地提高了设备的可用性，降低成本，赢回投资。

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 . Ventilation is not required in an enclosure having these minimum dimensions .EatonElectrical Sector1000 Eaton Boulevard Cleveland, OH 44122United States877-ETN-CARE (877-386-2273) © 2016 EatonAll Rights ReservedPrinted in USAPublication No. IL012043EN / TBG001166 Part Number: IL012043ENH03 January 2016Eaton is a registered trademark.All other trademarks are property of their respective owners.Instruction Leaflet IL012043EN Effective January 2016Instruction Leaflet for the LES/MES 310+ Electronic T rip UnitFigure 15.
