Abstract (en)
The invention relates to an electromagnetic trip device with percussion pin. The insulating actuation rod (20) of the percussion pin is anchored rigidly in a hole (27) conjugate with the ferromagnetic mobile core (17) to form a built-in connection. The rod (20) traverses a through-orifice (21) in a diaphragm (28) disposed in the bore (29) of the fixed core (19) in order to improve the dynamic behaviour during percussion. Applications: miniature electric circuit breakers. <IMAGE>
