Abstract
A circuit breaker equipped with an add-on remote control unit comprises a mechanical transmission link independent from the main mechanism, to transmit the position of the movable contact to an indicator, which automatically unlocks a latch in the open position to enable padlocking of a rack. The mechanical link is in two parts, composed of a push-rod associated with an operating lever on which the indicator is arranged, and a link rod articulated on the switching bar.
