Patent ID: 8526159

Claim:
An overvoltage protection device comprising a thermal disconnection device and a fault indicator as well as at least two first protection elements, specifically disc-shaped varistors ( 7 ), and at least one second protection element, specifically a gas arrester ( 9 ), each of the at least two first protection elements ( 7 ) having a connection pin ( 12 ), wherein the at least two first protection elements ( 7 ) and the at least one second protection element ( 9 ) are interconnected in a Y-arrangement, further comprising a device housing or supporting part for receiving the first and second protection elements and means ( 11 ) for mechanically preloading the thermal disconnection device, wherein the thermal disconnection device comprises a low-melting solder or the like means and the first protection elements ( 7 ) are arranged such that the connection pin ( 12 ) of one first protection element ( 7 ) is positioned opposite the connection pin ( 12 ) of the other first protection element ( 7 ) at a distance to form a distance space therebetween, and the thermal disconnection device is located mainly in the so formed distance space ( 13 ), characterized in that the thermal disconnection device further includes a bypass connection pin ( 15 ) of the second protection element ( 9 ) which directly bypasses the distance space and provides an electrical connection between the aforementioned connection pins ( 12 ) of the first protection elements ( 7 ) in the distance space ( 13 ) in a solder-contacted manner, and wherein the mechanically preloaded disconnecting component ( 5 ) includes a finger ( 16 ) which acts on the bypass connection pin ( 15 ) in such a way that, in the event of an overload, the bypass connection pin ( 15 ) is physically placed away from the connection pins ( 12 ) of the first protection elements ( 7 ).
