A release for an electrical switching arrangement is disclosed, which is arranged over the course of a first current path. In at least one embodiment, it includes at least two switching contacts, which are arranged in a housing and are isolated if the current flowing via the switching contacts has exceeded a predetermined threshold value, with an actuating element, which responds, counter to the force of a restraining apparatus, to a pressure which is generated by an arc drawn in the event of electrodynamic recoil of the switching contacts in an isolating zone of the switching contacts, which isolating zone is surrounded by the housing, and which actuates a shutdown mechanism which brings about automatic interruption of the current path, wherein the actuating element has a movable element, which forms a blocking element in a flow channel, which is connected to the isolating zone, which blocking element performs a predetermined control movement at the pressure which is intended to result in shutdown. |
