Control Circuit Fuse Block
These panel mounted fuse
holders, designed for control
circuit protection or other
similar low current
requirements, have extractor
type fuse caps. The Class CC
rejection type fuses (KTK-R)
used in these holders are
intended for use with
equipment designated as
being suitable for use on
systems having high available
fault currents. If branch circuit
protective device is 45A or
greater, C320FBR fuse kit
may be required for control
circuit protection per NEC
430-72.

Transient Suppressor Kits
NEMA Sizes 00–2
These kits limit high voltage
transients produced in the
control circuit when power is
removed from the contactor
or starter coil. There are three
separate suppressors for use
on 24–120V, 208–240V or
277–480V coils respectively.
These devices mount directly
to the coil terminals of
Freedom Series contactors or
starters NEMA Sizes 00–2
and lighting contactors 10–
60A. Reversing devices will
require two.
Product Selection
NEMA Sizes 3–5
This device mounts on top
of any side-mounted auxiliary
contact on Freedom Series
NEMA Sizes 3–5 and lighting
contactors 100–300A. It
connects across coil
terminals on any 120V
contactor or starter magnet
coil (reversing starters or
contactors require 2).
Limits high voltage transients
produced in the circuit when
power is removed from the
coil.
Product Selection
Shorting Bar Kits
These kits provide phase-to-
phase power connections of
contactors for field assembly.
The kits include bus
connections and mounting
hardware. The shorting bars
connect all three phases of a
single contactor.
