Bistable remote control device for controlling opening and closing of contact of interruption device in remote-controlled circuit breaker, has damping unit authorizing displacement of displacement part to drive transmission element

摘要

The device (1) has an electromechanical actuator i.e. monostable electromagnet (21), equipped with a small displacement part i.e. yoke (51), an excitation coil, and a movable part i.e. plunger core (45). A damping unit (57) is arranged between a support unit (58) of an insulating case (41) and a support face of the small displacement part to authorize displacement of the small displacement part along an actuating axis (46) by crushing the damping unit, so that the displacement of the small displacement part drives a movable transmission element (151) between two stable axial positions.
