Cautions and warnings:
- Surge arresters must not be operated directly in power supply networks. www.ishumba.com
- Surge arresters may become hot in case of longer periods of current stress (danger of burning). www.ishumba.com
-
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.www.ishumba.com
- Damaged surge arresters must not be re-used.www.ishumba.com
