ABSTRACT:
A narrow width molded case circuit breaker having a current limiting contact arrangement has the line side terminal brought external near the middle of an end wall of the breaker case. A large mass connector bar is loosely affixed to the terminal by a screw passing through openings in each and engaging a threaded sleeve disposed within a counterbore in the connector bar. The sleeve also engages a threaded post on a supply conductor and is rotated by the screw to clamp the connector bar between the supply conductor and terminal, providing an external current path for heat dissipation and increased spacing from the current limiting contacts.
