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                                                                                 
        1High discharge capacity, low residual voltage.
        2Overtemperature protection.
        3Failure indication and centralized remote signalling alarm dry contacts.
        4no follow current, no Leakage current.
