Abstract
An auxiliary tripping device is configured to interrupt a flow of current in the event of an undervoltage and/or a current pulse in a subordinate power circuit. The tripping device includes a spring element, a storage element which can be moved between a tensioned and a detensioned position, a trip element for tripping a trip mechanism of the electrical switching device and an activation element, the storage element being embodied in the tensioned position, when activated by way of the activation element, to emit the stored mechanical energy to the trip element. In an embodiment, a movably supported blocking element is provided, which is connected functionally 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 and in a second position the blocking element releases the storage element to perform a movement.
