Description
Bussmann fusible disconnect switches allow the user to select the
appropriate fuse which best suits the tripping characteristic for the
application. The various classes of fuses are described below.
Changing the fuse is convenient as the fuse links are isolated on both
the line and load side of the fuse.
Fuse Classes
Class J (LPS)
This fuse provides both time-delay for motor loads and a high degree
of current-limitation. Suitable for the protection of service entrance
equipment, feeder circuits, and branch circuits serving both motor
and non-motor loads.
Class T (JJS)
Suitable for the protection of service entrance equipment, feeder cir-
cuits, and branch circuits serving both motor and non-motor loads.
Class CC (LP-CC)
The Class CC fuse was developed specifically for a growing need in
the industry: a compact, space saving branch circuit fuse for motor
circuits. CC fuses can be used for protection of motors from ⁄Ω¢ to
10HP. A major feature of the CC fuse is that they are current-limiting.
This provides the benefit of protecting downstream components
against the damaging thermal and magnetic effects of short-circuit
currents. Class CC fuses are branch circuit rated and can be used on
branch circuits of electrical distribution systems.
Class L (KRP-C)
This 100% rated fuse is a high interrupting rating, current-limiting
device for the protection of service entrance equipment, feeder cir-
cuits and circuit breakers. It may be applied at continuous currents
up to its ampere rating. The 4 second minimum time-delay provided
allows this fuse to pass normal surges and to coordinate with ground
fault relays.

6 Pole
This conversion kit, in conjunction with two
standard 3 pole switches, allows the switches
to open or close simultaneously. Handle is
not included.
Mechanical interlock of two
standard switches
This conversion kit prevents one switch from
closing when the other switch is in the ON
position. Handle is not included.
