Product Description

QZS01-385/30(S) multi-layer graphite gap power supply lightning protector, which adopts laminated graphite gap and multi-point trigger technology inside,which improvesprotection level against transient surges. Therefore, it can be used for low-voltage power supply and distribution systems and electrical equipment to provide Class B (Class I classification test) lightning protection. The product has a built-in overtemperature and overcurrent protection function, with a remote signal alarm interface (dry contact), which is convenient for remote monitoring of surge protective device status.

 

Features

  • Greatly improves the protection level against transient surges
  • The product has built-in overtemperature and overcurrent protection function
  • With remote signal alarm interface (dry contact), which is convenient for remote monitoring of surge protective device status

Application

 

It can be used for low-voltage power supply and distribution systems and electrical equipment to provide Class B (Class I classification test) lightning protection.
