•All-purpose silver linked fuse for both overload and short-

circuit protection for high capacity systems (mains and large

feeders).

•Time-delay (minimum of four seconds at five times amp rating)

for close sizing.

•Current limiting action of the fuse generally affords consider-

able reduction in bus bracing.

•Interrupting rating of 300,000 amperes complies with

NEC Sections 110-9 and 230-65 for today’s large capacity

systems.

•O-ring seals maximize pressure build-up during current limiting

action and ensure filler retention.

•High grade silica-sand filler; accelerates response of fuse to

short-circuits by having quenching effect upon the fuse arc.

•99.9% pure silver fuselinks. The high conductivity of silver

gives low watt loss and low operating temperature at normal

current levels; minimizes total clearing I2t fault energy let-thru.

•Selective coordination (blackout prevention)

•Glass melamine tube.

•Silver plated end bells.

•Reducers not necessary.

O-RING SEALS

Formation of arc gas within fuse

body suppresses arcing; lowers

arcing I2t energy. O-ring seals

maximize pressure build-up during

current limiting action. Also volume

of sand is critical. Slight loss can

adversely impact on current limit-

ing action. O-ring seals insure filler

retention. They compensate to a

degree for switchgear misalign-

ment, and expansion and con-

traction of mounting surfaces

with change in load to no-load

conditions.

SAND FILLER

High grade silica-sand filler.

Accelerates response of fuse to

short-circuits by having quenching

effect upon the fuse arc.

Substantially contributes to current

limiting action.

99.9% PURE SILVER

FUSELINKS

Embody “silver-sand” design.

99.9% pure silver links; silica-

sand filler. The high conductivity of

silver gives low watt loss and low

operating temperature at normal

current levels; minimizes total

clearing I2t fault energy let-thru…

state-of-art fuse design. High

degree of current limitation holds

down fault currents and levels of

destructive energy. (Although other

link materials can provide current

limitation, they do not equal that

of silver.)

•Compact branch-circuit units with high interrupting rating

and current limitation.

•With a 600 volt rating, they can be used in 120/208,

120/240 and 277/480 volt circuits.

•Length variations relative to case size make the “rejection”

type fuses.

•In general, SC fuses are about ⁄Ω™ the size of the 600 V NEC

fuse type.

•SC fuses with ampere ratings above 6 amps have a degree

of overload time-delay which permits them to pass tempo-

rary overloads. At 200% load, they have a minimum open-

ing time of 12 seconds.

•Current-limiting devices designed specially for use on

welder circuits only.

•Time-current characteristics are designed to hold on the

intermittent overloading encountered in welder operation,

while providing short-circuit protection to the circuit and

equipment.

•Welder limiters have excess current capacity in the operat-

ing range as needed for this type of service.

•Because of the special characteristics of the welder limiters,

they are not intended for application on general-use circuits.
