Abstract
A locking device is for low-voltage circuit-breakers. It can travel into a frame including a lock and a control member to be activated through the lock. The control member interacts with an internal locking slide when a circuit-breaker is moved into the frame, the locking slide being displaceably guided in the circuit-breaker. If the locking device is activated (“locked”), the control member acts on the internal locking slide of the circuit-breaker and ensures that the circuit breaker cannot be switched on. If circuit-breakers with locking slides that can be displaced vertically are used, the control member is situated underneath the circuit-breaker.

An arrangement comprising:
- plug-in unit;
- a low-voltage power switch inserted into the plug-in unit, and provided with an internal locking slide which can be moved from a resting position to an activated position, wherein the locking slide controls an internal readiness controller;
- and
- a locking device fixed relative to the plug-in unit and including
- a lock for locking the internal locking slide in the activated position where an activation of the low-voltage power switch is prevented;
- and
- a control element that cooperates with the internal locking slide;
- wherein the control element is moveable from a non-activated first position to an activated second position;
- and
- wherein the lock functions to lock the control element in the activated second position.
