Features
Without open fuse indication
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
Offers a 10 sec time delay at 5 times the rated current
The time-delay feature makes it possible to use fuse amp ratings that are much smaller than those of non-time delay fuses
Provides current limitation to help protect downstream components from high fault currents
Gives motor running back-up protection to motors without extra cost
