摘要： A miniature circuit breaker having a pair of operable contacts in a main current path between a line terminal and load terminal, a trip mechanism for opening the contacts if an overcurrent condition occurs, and an electric motor to close the contacts via a contact closing mechanism. The trip mechanism includes a trigger mechanism and a contact opening mechanism, a current sensor arranged to detect current through the main current path, and a control unit. The trigger mechanism triggers the contact opening mechanism if a trip signal is produced. The control unit produces a trip signal to operate the trigger mechanism if it determines a short circuit condition occurs based on output of the current sensor; and the control unit is arranged to operate the electric motor to trigger the contact opening mechanism into opening the contacts independently of the trigger mechanism if it determines that an overload condition occurs.

摘要： An electronically driven trip actuator for multipole industrial rated molded case circuit breakers is installed within a common housing with the circuit breaker operating mechanism. The trip actuator consists of a mechanical actuator cooperatively connected with a magnetic latch. The magentic latch arrangement holds the trip actuator against an actuating spring bias. 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.
