Terms in accordance with ITU-T Rec. K.12 and DIN 57845/VDE0845
The arrester failsafe mechanism contains an insulating foil with a melting
temperature of 260 °C.
Arrester failsafe 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.
Surge arrester
3-electrode arrester
At delivery AQL 0.65 level II, DIN ISO 2859
In ionized mode
Test according to ITU-T Rec. K.12
Tip or ring electrode to center electrode
Total current through center electrode, half value through
tip respectively ring electrode.
Voltage of the current source 230 V
The short-circuit spring does not trigger until 260 °C is reached depending on the sensor material.
Care must be taken to limit the thermal radiation onto adjacent parts to safe values.
If the contacts of the surge arresters are defective, current stress can lead to the formation of
sparks and loud noises.
Surge arresters must not be operated directly in power supply networks.
Surge arresters may become hot in case of longer periods of current stress (danger of burning).
Surge arresters may be used only within their specified values. In case of overload, the head
contacts may fail or the component may be destroyed.
Damaged surge arresters must not be re-used.
