Protect your upstream personnel and investment

while increasing distribution reliabilityUsing expulsion fuses

where ignition of

combustible materials,

dry grass or worse, gases,

are a high potential risk,

is now unnecessary

because of Eatons Cooper

Power Systems ELF

current-limiting fuse.

Dont take that risk with

your upstream personnel;

preventing even one

accident is well worth

the investment.

The ELF dropout fuse is a fullyself-contained design thatoperates silently and eliminatesexpulsive showers associatedwith expulsion fuse operation.The full-range current-limitingrating ensures reliable operationof over-loads and fault currents.These features make it suitablefor areas where a high firehazard exists. The ELF-LR fusehas been granted permanent

exemption by the CaliforniaDepartment of Forestry andFire Protection (CAL FIRE)from power line distributionpole clearance requirements the trimming or removal ofbrush or trees from right-of-wayto reduce a potential fuelsource when the fuse isinstalled in the field accordingto manufacturers specifications,assuring that no gas, sparks,or debris is emitted.

Because of this assurance,you get all of the following

benefits:

Increased safety to linepersonnel during circuitenergization operations

Increased safety for personsworking in flammable orconfined areas of worksites

Reduced hazards and fire risk

Design

Moreover, the universal fitdesign of the ELF fuse makesit an easy retrofit into anyindustry standard interchange-able cutout. Because it hasa drop-open design, operationis clearly indicated and faultlocating is simplified. In longcable runs of upstream oil andgas applications, this will greatlyreduce time and money spenton upkeep of the system.Once the fuse has operated,maintenance personnel cansimply use a clampstick toremove the suspended fuse.

Energy-limitingDesign

With its full range, current-limiting characteristics testedto ANSI/IEEE requirements

C37.40, C37.41, and C37.47,the ELF fuse operates toclear both low- and high-currentfaults quickly. The elementconstruction, with separablelow-current and high-currentsections, controls peak arcvoltage levels, and limitscurrent and energy (I2t)let-through levels duringthe clearing operation.

This energy-limiting designallows for:

Reduced system damagefrom high energy faults inheavy loading upstreamapplications

Uninterrupted power qualitydue to sustained system-wide voltage support ontrips caused by faultswithin the system

Potential reduction in arcflash concerns and requiredpersonal protectionequipment (PPE)

Expulsion Fuse

ELF Fuse

Test parameters:6400 A RMS symmetrical.

Test results:ELF Current-Limiting Fuses Reduce Energy Let-Through

by a Factor of 9 over Expulsion Fuses.

Product scope

The ELF fuse voltage ratingsrange from 8.324 kV whileour single-, double-, and triple-barrel fuse designs expandamperage ratings from 680A for easy coordination. Thisexpanded offering allows oneto easily choose fuses that

work for almost any system.

Moreover, the ELF fuse isdesigned to be mounted in15 kV and 27 kV, (110 kV,125 kV or 150 kV BIL) ratedinterchangeable opendistribution cutouts includingMacLean/S&C Type XS,Hubbell Type Cand ABBType ICXcutouts. Designsfor use in 35 kV (170 kV BIL)rated ABB Series Vcutoutsare also available.
