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.
