摘要： An electronically driven trip actuator for multi-­pole industrial rated molded case circuit breakers is installed within a common housing with the circuit breaker operating mechanism. The trip actuator (27) consists of a mechanical actuator (29) cooperatively connected with a magnetic latch. The magnetic latch arrangement holds the trip actuator against an actuating spring bias (33). Upon receiving an appropriate signal response, the mag­netic latch releases, allowing the mechanical actuator to move into contact with the circuit breaker latch under the influence of the actuator spring. The ar­rangement of the mechanical actuator and actuator spring provides a low latching force to the magnetic latch, while providing a large trip force to the circuit break­er latch.

摘要： The neutral excitation transformer and differential current transformer (15,16) of a ground fault circuit interrupter device are mounted on a common electrically insulated support having downwardly extending pins for inserting into the printed wire board (18) of the electronic signal processor circuit. A metal can electromagnetic shield having four prongs extending from its bottom end is mounted to the support by means of three of the prongs while the fourth prong is inserted within the printed wire board for electrical connection with the signal processor circuit.
