    Tips: What is a surge protection device?

    The surge protection device (SPD) is an electronic device that provides a protection for electrical equipment, communication network etc. from the effect of surges. When a current spike or voltage surge suddenly occurs in an electrical circuit or a communication line due to external interference, the SPD can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit.
    Surge protection devices are designed to minimize the effects of the indirect and direct lightning or other transient overvoltage surges, suitable for surge protection in residential, tertiary industrial and other industrial applications. SPD has several protection modes: L-L, L-G, L-N, N-G and its combinations.
    SPD is an indispensable device for lightning protection in the electronic equipment. Its role is to restrict the transient overvoltage that enters the power line and signal transmission line to the voltage range that the device or system can withstand, or to discharge powerful lightning current into the ground, thus to protect the equipment or systems from shocks.

    Existing reviews of Surge Protection Device, Type 2, 20/40/60/80kA
    Easy installation
    The surge protection device has installed easily. I bought this for the lightning days in this summer and hope it will work as expected.

    Surge protection device is not expensive but does work.
    Very easy to install in the panel. This SPD is a good solution for surge protection without extra expense. Yeah, if you experience the lightning days like me before, you need this, not expensive but does work.
