Abstract

An alternating-current protective device comprising a housing, and a series of contact elements fixedly arranged in said housing, said fixedly arranged contact elements having movable contact bridges. A traverse serves for actuating said movable contact bridges. There is provided at least one separate contact element incorporating a contact element housing and a movable contact bridge. A plunger extends out of the contact element housing for actuating the movable contact bridge of said separate contact element. The separate contact element is positionable in the protective housing in a first position and in a second position turned through 180 DEG with respect to the first position. The plunger of the separate contact element bears against an impact surface of the traverse. The plunger has two end surfaces arranged behind one another to define a front end surface and a rear end surface. These end surfaces are arranged at the plunger with respect to the impact surface such that in the one position of the separate contact element the front end surface bears against the impact surface of the traverse for the early actuation of the separate contact element and in the other position of said separate contact element the rear end surface bears against the impact surface of the traverse for the late actuation of such separate contact element.
