Auxiliary Contacts — Mounting Positions
The sketches below illustrate the maxi-
mum number of auxiliary contacts that
can be assembled to a contactor and
their locations in standard enclosures.
Table 37-6. Auxiliary Contact Mounting Positions

Available positions on contactors or starters other than what is factory installed.

When a pneumatic timer is mounted on contactor, only side mounted auxiliary contact positions
are available. The solid-state timer, when added, takes up side mounted auxiliary contact
position.

For 100 – 400A contactors, a base auxiliary contact must be added in position L1 before additional
contacts can be mounted.
