Abstract

A surge protection device comprises at least one disconnecting device provided in a housing, a heat-conducting element, an actuating element for actuating an indicating device, and a locking element, the heat-conducting element being in contact with the housing. The actuating element is fastened to the heat-conducting element by means of the locking element, and the fastening is configured such that when a predetermined temperature at the locking element is exceeded, the locking element is detached from the heat-conducting element and/or from the actuating element and releases the actuating element.
