ABSTRACT:
A residential circuit breaker electromagnetic trip unit facilitates the assembly of the trip unit components by use of a pair of braid connectors for connection between the trip unit magnet and the circuit breaker contact arm. The trip unit bimetal is directly welded to the trip unit magnet and the braid connectors for reduction in material and labor costs. The contact arm and the magnet are shaped to present a parallel path connection between the contact arm and the magnet for close fit tolerance. The front surface of the magnet is configured to prevent magnetic adhesion between the magnet and the trip unit armature under intense short circuit overcurrent conditions.
