Section 1: General information
An auxiliary switch is an optional device providing
remote electrical indication if the circuit breaker is
open or closed. Up to three auxiliary switches can
be mounted in the circuit breaker. Each switch has
two normally open (“A”) and two normally closed
(“B”) contacts for a total of 12 available contacts.
Section 2: Installation of the
auxiliary switch
To install the auxiliary switch, proceed with the
following five steps:
Step 1: Remove the front cover by unscrewing
the hex head captive bolts (four for three-pole,
six for four-pole) that join the cover to the breaker
housing using a 10 mm 1/4-inch drive socket.
Then hold the charge handle down approximately
45 degrees to pull off the cover.
Step 2: Place the appropriate label on the
front cover nameplate space located under
“Accessories.”
