The short-circuit spring does not trigger until 180 °C is reached depending on the material. Care
must be taken to limit the thermal radiation onto adjacent parts to safe values.
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.
