Features and benefits
-
Dual-element feature provides the best time-delay performance, allowing closer sizing and superior protection of motors and transformers
-
Closer sizing allows for smaller fuses and less costly switches
-
Class RK5 fuses with a 200 kA interrupting rating for use in a broad range of applications
-
Provides motor overload, ground fault, and short-circuit protection
-
Helps protect motors against burnout from overloads and single-phasing when sized properly
-
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-second 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. Considerable cost savings occur by permitting the use of smaller size switches, panels, and fuses themselves.
-
Provides current limitation to help protect downstream components from high fault currents.
-
Gives motor running back-up protection to motors without extra costs.

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
