Abstract.- ELECTRIC CIRCUIT BREAKER WITH A REMOTE CONTROLLED STATIC SWITCH. the invention relates to a miniature circuit breaker. The function protection is ensured by the magnetothermal release (32) cooperating with the mechanism (30) to induce the opening of the contacts (22, 24). The function remote control results from the presence of a triac (56) series connected with the contacts (22, 24) and the release (32). The creation or breaking of the rated current happens by conducting or locking the triac (56) without calling out -the mechanism (30). The triac is automatically short-circuited when the are is switched on the lower horn (39) during the cut-off phase following the appearance of a fault current detected by the release (32). Refer to Fig. 2.
