ZGG40-150/275/320/385/440(3+0)hs 

General 
This series is made up of  MOV power modules and a base, used for secondary protection of L-PEN 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                                                                                 
1. Anti-reverse plug .
2. High discharge capacity, low residual voltage.
3. Overtemperature protection.
4. Failure indication and centralized remote signalling alarm dry contacts.
5. Enclosure IP20, UL94 V-0.
