Terms in accordance with ITU-T Rec. K.12 and DIN 57845/VDE0845
The arrester failsafe mechanism contains a insulating foil with a melting
temperature of 260 °C.
Arrester fail safe works at temperatures > 260 °C. The arrester has to be
fixed mechanically, if the arrester is contacted by soldering and if the solder
temperature is less than 260 °C.
