    Abstract: A high-current multipole circuit breaker is made up of standard poles juxtaposed in a molded case. At least two adjacent poles are twinned, that is to say electrically arranged in parallel and connected to a common connecting strip. The connecting strips of the other poles are widened, so as to partially overlap the immediately adjacent twinned pole. In this way, the circuit breaker rating is higher than that of the individual poles which make it up.

    Abstract: The circuit breaker is formed by two adjoined standard multipole molded cases, resin being cold-cast between the opposite side walls, comprising reliefs, of the two cases in order to provide fixing. A spacer, secured by bolts to the side walls of the two cases, defines their distance apart and can be used to cooperate with a racking cam when the circuit breaker is drawn into a fixed frame. The circuit breaker comprises an electronic trip device, an operating mechanism and an operating bar of the poles common to all the poles. At least two adjacent poles are twinned, that is to say eletrically connected in parallel.

    Abstract: A remote controlled circuit breaker including a mechanism linked to a handle by a drive lever equipped with a roller cooperating with a recharging cam of an energy storage system including a spring. A bearing surface is arranged to block the roller in the charged position, without requiring the presence of a special latching stage, since the line of action of the reaction R of the roller passes via the transmission shaft of the cam. A step-by-step motor of the vibrating type drives the transmission shaft in rotation, and enables almost instantaneous stopping of the cam when the roller is in contact with the bearing surface.

    Abstract: A stored energy system of a circuit breaker operating mechanism comprises a telescopic link having a guide and a cap with relative movement between which at least one closing spring is inserted. At the end of charging travel, a removable blocking device can be inserted in orifices of the cap and guide to lock the telescopic link. The release of a recharging cam by unlocking a closing pawl then causes a break in the mechanical link with a drive lever, so as to allow the sub-assembly formed by the telescopic link and the closing spring in the compressed state to be removed.

    Abstract: The electric control to reset a circuit breaker is formed by a sub-assembly (10) to be coupled to the mechanism (60) of the circuit breaker. At the end of the charging travel of the closing spring a control cam (46) disconnects and stops the motor. The charging position is defined by a latch interlocking the charging cam (62), a closing operation being induced by the release of the latch and a limited rotation of this charging cam (62). The link shaft between the motor reducing sub-assembly or block (10) and the mechanism (60) transmits this closing limited rotation to the control cam (46), which induces the restarting and the connecting of the motor for a reset operation of the closing spring.
