MODULE DE COMMANDE ET DE PROTECTION D'UN APPAREIL INTERRUPTEUR

摘要

The invention concerns a control and protection module (10) for a low-voltage multi-pole interrupter apparatus comprising a base (50), a control electromagnet (41) and a tripping element (42) designed to act on mobile contacts (52) to open or close the power poles. The removable control and protection module (10) comprises an electronic card (20) equipped with a processing unit (30), a control device (31) and a protection device (32) for actuating respectively the electromagnet and the tripping element in response respectively to a control signal (310) and a triggering signal (320) transmitted by the processing unit. The processing unit is capable of eliminating the control signal (310) of the electromagnet (41) in case of malfunction of the protection device (32).
