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 rat-
ing 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 prop-
erly
•
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 them-
selves.
•
Provides current limitation to help protect down-
stream components from high fault currents.
•
Gives motor running back-up protection to
motors without extra costs.
