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.
