Application:
This surge arrester is suitable for TN-C system.
Protection of an electrical installation and all electrical and electronic devices connected this installation against destructive overvoltage surges.
Surge arresters cover the protection of home appliances, commercial building equipment, and industrial equipment.
The devices are especially designed to provide complete and effective protection against surges, protecting equipment and property connected to the low voltage network.
It can be suitable for low-voltage AC power distribution system,rated voltage up to 380V,to protect from direct and indirect lighting impulse and other transient over voltage.
