CURRENT INTERRUPTER ABSTRACT OF THE DISCLOSURE A circuit interrupter for a power control system which is characterized by a circuit breaker and an electrically insulating housing, which housing comprises separable molded portions. The circuit breaker comprising at least two sets of pairs of movable and stationary contacts in stacked relationship, the stationary contacts being mounted on internal conductors extending through aligned openings in the housing and being connectable to external conductors. The housing has molded support means for retaining the internal conductors in stacked aligned positions. The movable contacts are mounted on movable contact means including bridging contact members and an actuator for moving the bridging contact members in unison between open and closed positions of the contact. Solenoid means are provided for closing the contacts. In addition, a slot motor can be provided on the bridging contact members for opening the circuit in response to a very high current overload in order to provide a current limiting type breaker. Finally, a current transformer can be provided on the internal conductors for opening the circuit in response to other current overloads.
