The present disclosure relates to a semiconductor circuit breaker and, more specifically, to a semiconductor circuit breaker having a detachable interface module. The semiconductor circuit breaker according to an embodiment of the present disclosure comprises: a circuit breaker body connected to a main circuit; and an interface module which is independent from the circuit breaker body, wherein the circuit breaker body comprises: a first reception part disposed on the outer surface of the circuit breaker body; and a blocking part including a power semiconductor device connected to the main circuit to block the main circuit when an overcurrent occurs, and the interface module comprises an operation part for controlling the blocking part, and is detachably coupled to the first reception part.

The present disclosure relates to a semiconductor circuit breaker, and more specifically, to a semiconductor circuit breaker provided with a detachable interface module. The semiconductor circuit breaker, according to one embodiment of the present disclosure, comprises: a circuit breaker main body connected to a main circuit and provided with a module receiving unit on the outer surface thereof; and an interface module provided independently from the circuit breaker main body and detachably coupled to the module receiving unit. The circuit breaker main body comprises: a terminal cover rotatably coupled to a terminal unit of the circuit breaker main body; and an interlock member provided to the circuit breaker main body and restricting or releasing the opening of the terminal cover. The interface module comprises an interlock driving unit for operating the interlock member.

A load break tool is disclosed. The load break tool includes a main housing; a sleeve having a first end and a second end coaxially mounted in the main housing and slidable between a retracted position and an extended position, wherein the second end of the sleeve remains in the main housing in the extended position; a clip assembly connected to the main housing for engaging a pull ring of a circuit isolating device; and a hook engaging terminal rotatably connected to the first end of the sleeve, such that the hook engaging terminal rotates relative to the clip assembly.

A magnetic connector for connecting an electrical unit to an electrical consumer unit includes at least one magnet, a conductive metal part secured to this magnet, a connecting cable fixed to the conductive metal part, and a cap made of plastic material overmoulded on the connecting cable, the conductive metal part and the magnet, except for a contact surface of the magnet intended to make contact with a metal part of the electrical consumer unit.

A circuit breaker housing for holding a switching device unit and a number of connection contacts for a connection line and/or a busbar. The housing has a first housing part and a second housing part. In the joined, assembled state, the housing parts form a front side and a rear side opposite said front side and at least one connection side and end faces located opposite one another. A holding chamber for a connection module having one of the connection contacts is provided on the front side and/or on at least one of the connection sides.

A crossbar assembly and a trip assembly comprising same are disclosed. The crossbar assembly according to an embodiment of the present disclosure comprises a crossbar and an instant bar. The crossbar and the instant bar can be rotatably coupled so as to be rotatable around the same rotary shaft. Therefore, the space required for rotation can be reduced to be less than when the crossbar and the instant bar are individually rotated. In addition, the crossbar can move in a longitudinal direction when coupled to the instant bar. Therefore, a metallic bar for movement of the crossbar is unnecessary. Therefore, interference between different-phase currents flowing through the trip assembly can be minimized.

An adapter is for a metering assembly. The metering assembly includes an electrical switching apparatus and a socket assembly. The socket assembly has a plurality of jaw members. The adapter includes a base member and a plurality of electrical contacts each coupled to the base member and structured to be mechanically coupled and electrically connected to a corresponding one of the jaw members. Each of the electrical contacts is structured to be electrically connected to the electrical switching apparatus.

The present disclosure relates to a circuit breaker comprising: a circuit breaking part in which contact points of a fixed contact and a movable contact are in contact with each other; and an energy accumulation part for accumulating energy of a closing spring for controlling contact between the fixed contact and the movable contact, wherein the energy accumulation part comprises: an electromotive energy accumulation part; and a manual energy accumulation part separated from the electromotive energy accumulation part by a manual energy accumulation spring, and engaged with the electromotive energy accumulation part by unit of external pressure so as to transmit an inputted rotational force to the electromotive energy accumulation part, thereby accumulating the energy of the closing spring.
