EL-Anti-lightning Surge Arrester

Spd-C20-1p-20kA

The surge arrester consists of a semi-conductor valve element that opens at certain conditions. At normal conditions of the system, the surge arrester has infinitely high resistance between the protected conductors and earthing circuit.At voltage increase due to atmospheric nature or system failure, the valve element opens and leads the excessive voltage to the grounded circuit. After reversion of the normal voltage the valve element closes. The arrester can endure high momentary overloading.

*** ATTENTION!!! A certified Electrician Installer is required for the installation of this product.
