Features:

•

Provides motor overload, ground fault

and short-circuit protection. When used in

circuits subject to surge currents such as

those caused by motors, transformers and

other inductive components, these fuses

can be sized close to full-load amps to give

maximum overcurrent protection

•

The time-delay feature makes it possible

to use fuse amp ratings which are much

smaller than those of non-time delay

fuses. Considerable cost saving occurs by

permitting the use of smaller size switches,

panels and fuses themselves

•

Provides a good degree of short-circuit

protection (greater current-limitation) to help

protect downstream components from high

fault currents

•

Gives motor running back-up protection to

motors without extra cost

•

Helps protect motors against burnout from

overloads and single-phasing when sized

properly

•

Simplifies and improves blackout prevention

(selective coordination ratios)

•

Dual-element fuses can be applied in

circuits subject to temporary motor

overloads and surge currents to provide

both high-performance, short-circuit and

overload protection
