Description

Rheem 44-ECSR-100-5PK Fuse – RK5 Dual-Element Time Delay, 100A, 1-7/64 in. diameter replaces .The time delay feature makes it possible to use fuse amperage ratings which are much smaller than those of non-time delay fuses Considerable cost savings occur 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 co-ordination 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
