Abstract
An overvoltage protection device having a printed circuit board, a varistor having a metal-oxide varistor body that has a face and a conductive metal layer deposited on the face where the varistor is connected to a first electrical connection terminal by a first connection track of the printed circuit board and a disconnection tab is disclosed. The disconnection tab being fastened directly to the metal layer by a thermofusible link and exerting a traction force on the metal layer so that the disconnection tab moves away from the metal layer and disconnects the electrical connection between the first terminal and the varistor in response to melting of the thermofusible link is also disclosed.
