ZGGH12.5-760(3+0)T
 
General                                                                                 
The ZGGH12.5-760(3+0)T Power Supply SPD is made up of three ZGGH12.5-760 Modular Power Supply SPD, 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. High discharge capacity, low residual voltage.
2. Overtemperature protection.
3. Failure indication and centralized remote signalling alarm dry contacts.
4. no follow current, no Leakage current.
