ZGG80/100/120 Series
General
This series is used for primary and secondary surge protection. The 3+1 and 1+1 configurations are composed of MOV and GDT power module for L-N, N-PE protection respectively. The 4+0 and 2+0 configurations are composed of MOV power module for L-PE, N-PE protection. 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
1High discharge capacity, low residual voltage.
2Overtemperature protection.
3Failure indication and centralized remote signalling alarm dry contacts.
4Enclosure IP 20, UL 94 V-0.
