ZGG40-275/320/385/440(3+1)hs
General
This series is made up of three MOV power modules, one GDT power module and a base, used for secondary protection of L-N, N-PE respectively. It is applied in low voltage AC power distribution system, and connected between the AC power supply and the equipment in parallel. It can prevent the equipment from the impulse surge and the transient overvoltage caused by the outside environment (such as lightning, EMI, etc.) or by the system (such as switching effects of the system, startup or shutoff of the inductance and capacitance load, etc.) .
Features
1Anti-reverse plug and anti-mutual insert.
2High discharge capacity, low residual voltage.
3Overtemperature protection.
4Failure indication and centralized remote signalling alarm dry contacts.
5Enclosure IP 20, UL 94 V-0.
