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).
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.
Surge arrester with triggered short-circuit mechanism must not be re-used.
