<p>The overvoltage protection containing at least one non-linear resistance element, connection points for its connection to the protected circuit and a device for temperature initiated disconnection of a non-linear resistance element from the protected circuit, while the device for temperature initiated disconnection of a non-linear resistance element from the protected circuit contains by means of a heat of the non-linear resistance element disconnectable tight joints created parallel to the current-conductive track and made of leadless solder of required strength but of a worse electrical conductivity, further it contains by means of a heat of the non-linear resistance element disconnectable conductive joints created in the current-conductive track and made of low strength electrical conductive leadless solder.</p> |
