Cautions and warnings
●
●
●
●
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).
If the contacts of the surge arrester are defective, current stress can lead to the formation of
sparks and loud noises.
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.
