Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

The present invention relates to an arc eliminator, and more particularly, to an arc eliminator with an earth contact. An arc eliminator comprises: a housing; an extinguisher installed on the housing; and an earth contact that is installed on the housing and protrudes out from the housing in such a way as to be connected to the ground bus bar provided inside a distribution board when the extinguisher is moved to a first position where the extinguisher is connected to a fixed bus bar provided inside the distribution board, and to be disconnected from the ground bus bar when the extinguisher is moved to a second position where the extinguisher is disconnected from the fixed bus bar.

A branch box (100) includes: a branch portion (21) branching a power path (205A) into at least two branch paths (206A, 207A); a fuse (60) located on at least one of the branch paths; a conductive member (33) connecting the branch portion and the branch path having the fuse; a first housing portion (11) receiving the fuse and closing its opening with a lid portion (81) to define a housing space; and a second housing portion (12) receiving the branch portion. The first housing portion is sealed with a first sealing material (85) filling a gap between the lid portion and the opening and is out of contact with the fuse. The second housing portion is sealed with a second sealing material (86) independent from the first sealing material. The conductive member passes through a partition wall (25) separating the first housing portion and the second housing portion.

A high-voltage combined electrical apparatus includes a transformer, at least one circuit breaker, at least one oil/gas separation module and at least one operating mechanism. In an embodiment, the circuit breaker includes a ceramic insulator, an upper outgoing line seat, a lower outgoing line seat, and a disconnecting mechanism connected there between. The oil/gas separation module includes a first end electrically connected to a transformer coil of the transformer, and a second end electrically connected to the lower outgoing line seat. The operating mechanism is connected to and controls the disconnecting mechanism. The high-voltage combined electrical apparatus of an embodiment integrates a circuit breaker and a transformer, omitting the conventional transformer oil/gas sleeve and overhead line, so that the structure thereof is simpler, the cost is lower, the area of ground occupied by the equipment is reduced, and the occurrence of short circuits associated with overhead lines is avoided.
