1. A remote controlled circuit breaker, comprising:
- a multipole circuit breaker unit including an insulating case, each pole of the multipole circuit breaker unit being housed in the insulating case and including a system of separable contacts which is driven by a rotatable switching bar between open and closed positions; and
a remote control unit for fitting onto the multipole circuit breaker unit, said remote control unit including;
lockout means for locking the system of separable contacts in an open position, said lockout means comprising an extractable rack;
an operating lever including a transmission finger and a latching part, said latching part being adapted to latch said extractable latch of the lockout means to prevent extraction of the latch;
display means for displaying open or closed positions of said system of separable contacts, said display means being provided on said operating lever; and
a mechanical transmission link which connects the operating lever to the switching bar, said mechanical transmission link comprising a link rod which is articulated on the switching bar, and a push rod which connects the link red to the transmission finger of the operating lever, whereby the operating lever is driven via rotation of the switching bar.

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.
