4.4 Plug-in and draw-out technology
A total of nine auxiliary circuit connectors can be installed depending on the size of the
molded case circuit breaker and the size of the plug-in or draw-out socket. The slots for
auxiliary circuit connectors are labeled from right to left in the socket, starting at 1.

Cable cages are used to attach the breaker-end half of the auxiliary circuit connector to the
underside of the molded case circuit breaker. Slot numbers are also printed on the cable
cages. The design of the cable cages for the top and bottom halves of the molded case
circuit breaker is different so that the cages cannot be mixed up or installed in the wrong
position. The fixing tongues of the breaker-end half of the auxiliary circuit connectors latch
into small recesses in the cable cages which are screw-mounted to the rear panel of the
circuit breaker. The auxiliary circuit connectors are securely fixed once the cable cages have
been installed.
