ABSTRACT:
A method of manufacturing a circuit breaker comprises the steps of preassembling the movable parts of the circuit breaker between a pair of frame members and providing a housing that is configured for supporting the unitary breaker assembly without attachments. Other circuit breaker components, attached to the unitary breaker assembly, are also supported in the housing without attachments. A cover is secured to the housing to complete the circuit breaker. Another version of the invention preassembles the movable parts of the circuit breaker and the stationary contact mechanism and trip coil, with the line and load terminals attached, between a pair of supporting frame members to form an operable circuit breaker module. The module is in turn supported in a housing without attachments. The circuit breaker module may be tested and adjusted prior to final assembly.
