Dimensional drawing
Cautions and warnings
Surge arrester must be selected so that the maximum expected follow current can be quenched.
The follow current must be limited so that the arrester can be properly extinguished when the
surge has decayed. The arrester might otherwise heat up and ignite adjacent components.
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.
