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.
Claims14
A surge protection device, comprising 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, and
- the actuating element being fastened to the heat-conducting element by means of the locking element, and the fastening via the locking element being 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,
- wherein the surge protection device has at least two disconnecting devices each having a housing, the heat-conducting element being in contact with at least two of the housings.
A surge protection device, comprising 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, and
- the actuating element being fastened to the heat-conducting element by means of the locking element, and the fastening via the locking element being 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, and
- wherein the surge protection device has an indicating device which includes an indicating area, a first indicating surface fixed in the indicating area, and a movable second indicating surface,
- the second indicating surface being movable between an arrested position in which the second indicating surface overlaps the first indicating surface, and a released position in which the second indicating surface is arranged offset with respect to the first indicating surface.
