Advanced protection, energy efficient Class RK5 dual element, current-limiting, time-delay fuses with optional open fuse indication on select ratings. Dual-element feature provides the best time-delay performance, allowing closer sizing and superior protection of motors and transformers. 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.

Class RK5 fuses with a 200kA interrupting rating for use in a broad range of applications. The time-delay feature makes it possible to use fuse amp ratings that 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. Gives motor running back-up protection to motors without extra costs.
