摘要： A switch unit, preferably implementing a circuit breaker, includes a contact slide unit formed by a contact slide, a fixed contact piece and a moveable contact piece), and a short-circuit release that acts to displace the moveable contact piece by means of a tappet in the event of a short-circuit. A moveable braking device is configured and arranged such that, following circuit opening displacement of the moveable contact piece in response to a short-circuit, the moveable brake device dampens the return, rebound movement of the moveable contact piece to reclose the circuit.

摘要： The present disclosure relates to an electrical protection system , including a breaker enclosure and associated terminals, and the methods of use therefor that allow for a circuit breaker or other electrical protection device to be safely added or removed from a circuit while power is supplied to at least one of the terminals. The disclosed enclosure and terminals include a series of interrelated safety features that prevent a user from accidentally completing the circuit from one terminal to another when the electrical protection system would be in an unsafe state. The combination of features described herein allow for a replaceable electrical protection device for equipment under load to be realized, thus improving user safety.

摘要： A multi-pole circuit interrupter configured to be coupled between an AC source and an electric load electronically detects a hazardous condition associated with energizing of poles and responds to overcome the hazardous condition using a solenoid. The multi-pole circuit interrupter comprises a first switch to energize a first pole on a phase A conductor of the multi-pole circuit interrupter and a second switch to energize a second pole on a phase B conductor of the multi-pole circuit interrupter. The multi-pole circuit interrupter further comprises an electronic solid-state circuit coupled to the phase A conductor and the phase B conductor to detect a line voltage variation and control a current to a device in response to trip an energized pole among the first pole and the second pole if only one of the first pole and the second pole is energized when a user controls a tie bar to turn ON or turn OFF the multi-pole circuit interrupter or when a trip bar fails to trip one of the first pole and the second pole.

摘要： A circuit breaker with quick response and separation and a quick response and separation method for the circuit breaker. The circuit breaker comprises a breaking contact group and a joint contact group. The breaking contact group comprises a movable breaking contact. The joint contact group comprises a movable joint contact. A movable contact limiting device used for limiting moving positions of the breaking contact and/or the joint contact is arranged between the breaking contact group and the joint contact group. The quick response and separation method for the circuit breaker comprises a breaking and opening step, wherein the breaking contact moves in a reverse direction and is separated independently ahead of the joint contact, or the breaking contact and the joint contact both move in a reverse direction and are separated at the same time.
