Abstract
The invention relates to a device for both mechanical and electrical lockout of a remote control unit for a modular circuit breaker. This device includes a retractable ring pivoting around a spindle and provided with a locking nose arranged to cooperate with a stop pin located on the circumference of a drum rotating around a spindle and bearing a manual control handle having two stable positions. The retractable ring bears in addition a rocker designed to actuate a switch fitted on the electrical supply circuit of the remote control unit. This device is advantageous in that it also enables padlocking or sealing of the retractable ring.
