IZM9 circuit breaker 2-way interlock
(1) Only qualified electrical personnel should be permit-
ted to work on the equipment.
(2) Always de-energize primary and secondary circuits
if a circuit breaker cannot be removed to a safe work
location.
(3) Drawout circuit breakers should be levered (racked)
out to the DISCONNECT position.
(4) All circuit breakers should be switched to the OFF
position and mechanism springs discharged.
Failure to follow these steps for all procedures described
in this instruction leaflet could result in death, bodily
injury, or property damage.
Section 1: General information
The mechanism linkage device can be used to interlock two
to three IZM circuit breakers. Mechanism interlocking holds
one or more circuit breakers tripped (prevents closure). An
operating lever assembly is installed on each circuit breaker
and interfaces with the main shaft and the tripper bar. The
lever assemblies are interconnected with cables. These
cables can be used for any orientation of the circuit breaker.
All IZM circuit breakers must use Type I and Type II kits.
