Abstract

A switchgear cubicle or a switching installation has a door (7) as the termination of the installation space of a switching device (1), for example of a low-voltage power circuit breaker. A locking device (11) is used for locking the door (7) against opening when the switching device (1) is switched on. For this purpose, the locking device (11) has a locking tab (21) fitted on the inner side of the door (7) and a locking lever (12), interacting with the locking tab, which is supported such that it can pivot vertically close to a lower lateral support (5) of the switching device (1) and is movable against the effective direction of gravity, by means of an opening spring (22), into an open position. The locking device is especially suitable for installations having fixedly installed switching devices. <IMAGE>
