ABSTRACT:
A protection switch, particularly for rapid quenching of electrical arcing, includes at least one single-pole protection switch module having a housing, a movable contact mounted on a switching arm for pivoting against a fixed contact between a closed position and an open position and a quenching device for quenching electrical arcing of the switch. The quenching device includes a quenching chamber with an inlet and an outlet for the arc. A first running rail connects the fixed contact with a first side wall of the quenching chamber and a second running rail connects a stopping surface, against which the movable contact abuts in the open position of the switching arm, to a second side wall of the quenching chamber. A separation strip extends substantially from side wall to side wall at the outlet of the quenching chamber.
