Abstract
An interlock assembly for a high amperage molded case circuit breaker is provided with a slide biased to interfere with movement of a push to close link whose operation enables discharge of the breaker closing spring. The slide is operated by the toggle assembly in the event the contacts are open to permit operation of the link except if the breaker is being tripped or held tripped. A trip solenoid of the permanent magnet type is reset, when tripped, by a reset spring under control of blade carrier which has excess energy available.
