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
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.
