Auxiliary tripping device for an electrical switching device and electrical switching device

An auxiliary tripping device for an electrical switching device, the electrical switching device being configured to interrupt a flow of current in an event of at least one of an undervoltage and a current pulse in a subordinate power circuit, the auxiliary tripping device comprising:

• a spring element;
• a storage element connected to the spring element, the storage element being movable between a tensioned position and a detensioned position;
• a trip element for tripping a trip mechanism of the electrical switching device;
• an activation element connected to the trip element, wherein the storage element is connected to the spring element such that the storage element stores a mechanical energy of the spring element when the storage element is in the tensioned position, wherein the storage element emits the stored mechanical energy to the trip element when the storage element is in the tensioned position and activated by the activation element;
• and
• a movably supported blocking element located adjacent to the storage element, the blocking element being functionally connected in a first position to the storage element when the storage element is in the tensioned position so that the storage element is held by the blocking element, the blocking element being configured to, in a second position, release the storage element to allow the storage element to perform a movement.
