Exe explosion-proof lightning protection box

Introduction： This product adopts the box structure and the sealed internal device has strong waterproof, dustproof and anti-corrosion properties and is completely free of arc. Leakage.It has EX explosion-proof function certification, more effectively play a role in protection.It’s suitable for the three-level lightning protection of the total power supply in the special operating environment of buildings, computer rooms, factories, enterprises, etc.,it also can effectively suppress the over-voltage on the power line,ensuring the safe operation of electronic equipment and other electrical equipment.
