  • Molded case circuit breaker with adjacent pole mechanisms spaced closer than adjacent terminals
    Patent number: 4554423
    Abstract: A molded case circuit breaker includes first and second pairs of separable electrical connectors disposed in adjacent poles of the circuit breaker and spaced apart by a spacing less than the spacing between externally extending electrical terminals for making external electrical connections to the same adjacent poles of the circuit breaker. The closer spacing is achieved by a plurality of integrally formed, molded projections formed in the base of the molded case of the circuit breaker for positioning movable portions of the lower electrical contacts spaced apart in the base by the above closer spacing.
