A trip interlock assembly 20 trips a circuit breaker 32 any time the circuit breaker is removed from its panel mounting. The trip assembly is adapted to be disposed about a load side terminal 24 and cooperate with the circuit breaker tripping apparatus. In one embodiment, the trip assembly includes a housing 50 and a spring-loaded actuation arm 48, disposed generally perpendicular to the circuit panel surface. The actuation arm is formed with a cam surface 100 which cooperates with a trip pin 106 adapted to actuate said circuit breaker tripping means. The trip pin acts as a cam follower and rides along the cam surface formed in the actuation arm. When the actuation arm is in an inward position the trip pin is in a normal position. However, when the circuit breaker is removed from the panel, the actuation arm under the influence of a biasing spring 78 moves outwardly. This causes the cam surface on the actuation arm to actuate the trip pin to trip the circuit breaker. In an alternative embodiment 220 of the invention, the trip interlock assembly includes a bell crank 226 with a reciprocally mounted plunger 228 which actuates an armature in the tripping means directly, instead of by way of the trip pin, anytime the circuit breaker is removed from its panel housing.
