Eatoncontinues to build onthe technology legacyby engineering highperformance, cost-effectivepower fuse products.Eaton’s medium voltagefuses are manufactured andtested to the requirementsof the C37-4X series ofstandards that are maintainedand updated regularly tomaintain currency withindustry practices. Thesestandards are:IEEE Std.

C37.48.1™IEEE Guide for theClassification, Application,and Coordination of Current-Limiting Fuses with RatedVoltages 1–38 kV.A better understanding ofsome fuse terminology willhelp you understand andselect the correct fuse. Thefollowing is a brief overviewof those terms.Power vs. DistributionThe differentiation is intendedto indicate the test conditionsand where fuses are normallyapplied on an electricalsystem, based on specificrequirements for generatingsources, substations anddistribution lines. Eachclass has its own uniqueset of voltage, current andconstruction requirements(see C37.42, .46 and .47).Low vs. Medium vs.High VoltageWhile fuses are defined inthe ANSI standards as eitherlow or high voltage, Eatonhas elected to name theirfuses to correspond with theequipment in which they areinstalled. Therefore, per ANSIC84, our fuses are namedas follows:●Low voltage—1000V andbelow●Medium voltage—greaterthan 1000 to 69,000V●High voltage—greater than69,000VV14-T1-2V14-T1-31.1Fuses GeneralProduct OverviewExpulsion vs. CurrentLimiting (Definitions per ANSI C47.40-1993)An expulsion fuse is a vented fuse in which the expulsion effect of the gases produced by internal arcing, either alone or aided by other mechanisms, results in current interruption.A current limiting fuse is a fuse that, when its current responsive element is melted by a current within the fuse’s specified current limiting range, abruptly introduces a high resistance to reduce current magnitude and duration, resulting in subsequent currentinterruption. Refer to Fuse Types Protection Range figure below for a features comparison.An expulsion fuse is not current limiting and as aresult limits the duration of a fault on the electrical system, not the magnitude.Current Limiting Fuse TypesThere are three current limiting fuse types: Backup, General Purpose and Full Range. It is important that the user have an understanding of these definitions to ensure proper application of the fuse (see Fuse Types Protection Range figure below).Backup FusesA fuse capable of interrupting all currents from themaximum rated interrupting current down to the rated minimum interrupting current.Backup fuses are always used in a series with another interrupting device capable of interrupting currents below the fuse’s minimum interrupting current.General Purpose FusesA fuse capable of interrupting all currents from the rated interrupting current down to the current that causes melting of the fusible element in no less than one hour.General Purpose fuses are typically used to protect feeders and components such as transformers.Full Range FusesA fuse capable of interrupting all currents from the rated interrupting current down to the minimum continuous current that causes melting of the fusible element, with the fuse applied at the maximum ambient temperature specified by the manufacturer.General High Voltage Fuse ComparisonFuse Types Protection RangeExpulsion Current Limiting VentedSealed Electromechanical StaticInterrupts at current zeroLimits fault currentGenerally higher voltage and current application capabilitiesGenerally higher interrupting ratings Different time/current characteristicsDifferent time/current characteristicsC u r r e n t L i m i t i n g T y p eInterrupting Currenti i hr.i min.i max.i max. — Maximum rated interrupting current i min. — Minimum rated interrupting currenti hr. — Current causing element melting in 1 houri — Any current melting element with no time limitGeneral Fuse Component TermsFuse Refill Unit (of an Expulsion Fuse)A fuse refill unit is a replaceable assembly containing the calibrated current-responsive fuse element and certain other items that facilitate current interruption. On its own, the refill unit has no interrupting ability. A refill unit must be mounted in a fuse holder with a spring assembly to form a refillable fuse unit. The refill unit is the section of the fuse that must be replaced after a fuse operation.Fuse Holder (of an Expulsion Fuse)A fuse holder is a reusable holder that when equipped with a fuse refill unit forms a fuse unit, capable of interrupting an overload or fault current. A fuse holder is supplied with a spring and shunt assembly, necessary to complete the internal interrupting assembly. The spring and shunt assembly is supplied with the fuse holder but is also available as a replacement part, as it may need replacement after several of heavy operations.Fuse UnitA fuse unit is a replaceable unit or assembly that isable, on its own, to perform current interruption. Inthe case of a refillable fuse unit, the refill unit must be replaced after a fuseoperation. Where a complete fuse unit is supplied from the factory, the complete fuse unit must be replaced after a fuse operation. All current-limiting fuses are fuse units.Exhaust Control DeviceWhen expulsion fuses are used in enclosures, exhaust control devices (filters,condensers or mufflers) are used to control the sound of the fuse operation, and to de-ionize and absorb the fuse exhaust products. These devices are normally supplied separately, because ofdifferent characteristics and ratings. They are reusable but may need replacement after several heavy operations.MountingA mounting provides all the necessary parts to safely mount a fuse in its intended piece of equipment. The base is the metal support to which all other pieces attach. Insulators attach to the base and insulate the live fuse unit from the base and everything beyond the base. Live parts are the parts of the mounting that are energized onceelectricity is flowing. The live parts provide the means to hold the fuse unit in place, electrical contact, and a place to make line and load connections.Non-Disconnect Mounting A non-disconnect mounting does not provide a means for removing the fuse unit until the circuit is dead and the fuse unit can be removed manually. The fuse unit is held in place by friction through the use of fuse clips or by a cross bar.1.1Fuses GeneralProduct OverviewDisconnect MountingThe disconnect mountingallows the fuse unit to beremoved (off load) using aninsulated switch stick. Theswitch stick grabs a pull ringand disconnects the fuse unitthat may then be lifted out ofits mounting.Dropout MountingDropout mountings areused in outdoor applications.The fuse unit is equippedwith a mechanical trigger thatunlatches the upper contact,allowing the fuse unit to dropout, increasing the dielectricseparation, and providingvisible indication of ablown fuse.Live PartsLive parts were brieflydiscussed as part of the“Mounting” definition.Everything above theinsulators on the mountingexcluding the fuse unit, fuseholder, and the fuse endfittings (if required) areconsidered the live parts. Fuseend fittings are discussednext and are not requiredwith non-disconnect liveparts, but are required andincluded with disconnect liveparts. Live parts may be soldseparately as replacementparts or for new OEMapplications.End FittingsEnd fittings are metal partsthat attach to each end of afuse unit’s ferrules (end caps).As previously mentioned,they are used solely withdisconnect fuse applicationsor when converting a non-disconnect to a disconnectfuse configuration.When end fittings areordered, a fitting for each endof the fuse is included. Keepin mind that end fittings canbecome damaged in use and,therefore, are sold separatelyfrom the live parts whennecessary. It is not necessaryto purchase an entire set oflive parts when only the endfittings are required.V14-T1-4。
