ZGG30-750(3+0)
General                                                                                 
        The ZGG30-750(3+0) Modular Power Supply SPD is made up of  MOV power modules and a base, used for secondary protection of L-PEN. 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.) .
