Three phase power supply, lightning protection, surge protector, box type, lightning counter, indicator lamp

Brief introduction

   The three phase power supply lightning protection box is used for lightning protection of 220/380V distribution system, so as to protect the equipment from damage caused by lightning overvoltage along the power line. It is mainly installed in distribution rooms, distribution cabinets, AC distribution panels, switchgear boxes and other important equipments, which are easily subject to lightning incoming power supply.

Working principle of product

   n the normal working condition, the lightning protection module is in the disconnected state and does not affect the normal work. When the line has the impulse overvoltage at the moment when the lightning strikes, the lightning arrester module quickly passes through the very short time, short the overvoltage to the earth, and when the pulse overvoltage disappears, the lightning arrester module is resumed to disconnect. State, which does not affect the power supply of the user.
