Molded case circuit breaker multiple accessory unit

Molded case circuit breaker having a combined trip actuator and accessory unit comprising:

• a molded plastic circuit breaker cover and case, said cover defining an enclosure space;
• a circuit breaker operating mechanism within said case and having means separating a pair of contacts to interrupt circuit current through said contacts;
• a trip actuator-accessory unit within a first recess in said circuit breaker cover proximate said circuit breaker operating mechanism which interacts with said circuit breaker operating mechanism to separate said contacts automatically upon overcurrent conditions through said contacts and to interact with said operating mechanism upon receipt of a remote trip signal;
• an electric switch-electronics unit within a second recess in said circuit breaker cover, an electric switch in said electric switch-electronics unit which interrupts said remote trip signal upon separation of said contacts and a printed circuit board in said electric switch-electronics unit providing operating power to said trip actuator-accessory unit;
• wherein said trip actuator-accessory unit includes an undervoltage coil arranged for providing a magnetic holding force to hold a trip armature against the bias of a charged compression spring;
• and including a flux shift coil within said trip actuator-accessory unit for diverting said holding force away from said armature to allow said armature to interact with said circuit breaker operating mechanism upon occurrence of said overcurrent condition.
