7.2 Secondary Disconnect
The secondary disconnect, illustrated in Figure 30, pro-
vides connections between the breaker control circuits and
external circuit elements. It is attached to a mounting
plate on the breaker back frame. It automatically makes or
breaks the control circuit connections as the breaker is
racked in or out of its compartment. Figure 31 illustrates
the numbering of the terminals in the secondary
disconnect.
Secondary Disconnect Removal
To remove a secondary disconnect, use the following pro-
cedure, as illustrated in Figure 32.

2. Remove the two screws and standoffs securing the
disconnect to the mounting plate.
3. Slide the disconnect mounting feet out of the slots
in the mounting plate. Remove the spring washer if
it has detached from the molded pin on the under-
