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)
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

•
•
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:
•
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
20 kA Vdc
Agency information:
•
•
Dual-element feature provides the best
time-delay performance, allowing closer
sizing and superior protection of motors and
transformers
•
Provides motor overload, ground fault, and
short-circuit protection
•
Helps protect motors against burnout from
overloads and single-phasing when sized
properly
* Open fuse indication available by inserting the sufix
“ID.” E.g., FRS-R-15ID.
