A power disconnection device for manually disconnecting power of a battery pack, the device including a housing, first and second interlock terminals provided in the housing and connectable to an interlock circuit of the battery pack, first and second high voltage terminals connectable to a high voltage line of the battery pack, a switch lever disposed over inner and outer portions of the housing, a first switch module in contact with the first and second interlock terminals, and upon an off operation of the switch lever, configured to be separated from any one of the first and second interlock terminals, and a second switch module configured to interlock with the first switch module, the second switch module being in contact with the first and second high voltage terminals, separated from any one of the first and second interlock terminals, and then separated from the first and second high voltage terminals.

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.

The present disclosure relates to an interlock mechanism for automatically locking and unlocking a lock system of an electrical cabinet based on the state of bolted pressure contact switches housed within the electrical cabinet.

An interlock system for an enclosure can include a power switch movable between an OFF position and an ON position with a defeater arm coupled to the power switch. The defeater arm can be selectively movable between a locked position and an unlocked position and when the defeater arm is in the locked position the power switch is prevented from moving from the OFF position to the ON position. An interlock can include a pivot bracket pivotally supported by a support bracket within the interior of the enclosure and movable between a first orientation, in which the pivot bracket is out of engagement with the defeater arm, and a second orientation, in which the pivot bracket displaces the defeater arm into the unlocked position. When the door is moved into a closed position from an open position, a door bracket displaces the pivot bracket into the second orientation.

An operating modes selector is for an earthing switch that includes power contacts and a motor for moving the power contacts. The selector includes a plurality of positions corresponding respectively to various operating modes of the earthing switch, and includes cams whose positions are defined by the selector position. The selector contains a first cam which pulls a first locking organ designed to mechanically block the motor of the earthing switch when the selector is in a position corresponding to a locked closed mode wherein the earthing switch is closed.
