SPD

SPD (Surge Protection Device or called surge arrester) is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold. We have spark gap, MOV and Spark tube type for different protection area. Surge Protector catalogue download.
