Features:

•

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.
