Description

KAZ is a non-fuse actuator (not a fuse) for use in

parallel with a 50 amp or greater fuse to provide

indication a fuse has opened by opening at 10 or

more amps. The KAZ can also be applied in a 1-, 2-

or 3-pole block with miniature signaling switches

to provide remote status indication.

MIS fuses are non time-delay pin indicating

supplemental fuses used to provide a visual

indication of an open fuse condition.

Features

KAZ (not a fuse)

• Connects in parallel with fuses having a rating

of 50 amps or more

• Opens at 10A or more

• Use with Bussmann signal blocks to actuate

a miniature switch that closes a signal circuit

when the KAZ pin indicator ejects upon opening

• Gives a direct visual indication of an open fuse

by the ejected, spring actuated pin

• UL Listed as “fuse accessory”

• Mounts in Bussman signal blocks 2778 (1-pole),

2837 (2-pole) and 2838 (3-pole)

MIS (non time-delay fuse)

• Gives a direct visual indication of an open fuse

by ejected (spring actuated) pin

• Can be used in circuits of 600Vac or less

• 200kA Interrupting rating

Typical applications

KAZ

• Large shunt-trip fused switches

• Fuse-protected circuits rated 50 amps or more

with shunt-trip devices

MIS

• 480V Control circuits

• PLC Circuits
