ZGG40-75/275/320/385/440(1+1)hs
General
This series is made up of one MOV power modules, one GDT power module and a base.
The ZGG40-75(1+1)hs is used for secondary protection of L(＋)-N(－), N(－)-PE respectively. It is applied to the low-voltage AC power distribution system or DC power supply and connected with equipment in parallel.
The ZGG40-275/320/385/440(1+1)hs are used for secondary protection of L-N, N-PE respectively.
Features
1Anti-reverse plug.
2High discharge capacity, low residual voltage.
3Overtemperature protection.
4Failure indication and centralized remote signalling alarm dry contacts.
5Enclosure IP20, UL94 V-0.
