Fusetron™ 600 V Class RK5, FRS-R — 600 Vac/300 Vdc,
1/10-60 A, dual element, time-delay fuses
Catalog symbol:
•
•
•
FRS-R-(amp) (non-indicating)
FRS-R-(amp)ID (indicating)
•
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.
Description:
•
Advanced protection, energy efficient
Class RK5 dual element, current-limiting,
time-delay fuses with optional open fuse
indication on select ratings
Time-delay – 10 second (minimum) at 500%
of rated current

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
