Varistor terminals

Varistor terminal blocks are designed to limit electric circuits load peaks formed on the switchgear, to protect circuits from pulse overvoltage, to limit overvoltage surges on phase voltage, or to limit the sources of disturbing voltage on closing contacts. Varistor terminals are not the standard protection from lightning current overvoltage. The terminal includes a side barrier and the terminal is thus delivered encapsulated. Protection degree IP 20.
