AC SPD Type 1 Voltage Limited Type Surge Protective Device is a type of surge protection device that is designed to protect electrical equipment from voltage surges and spikes caused by lightning strikes or other electrical disturbances.
●Varistor surge protective device (AC SPD)
●Large discharge energy.
●No leakage and no follow current.
●Applied to surge protection at the first stage of the power supply system.
●Strong environmental resistance.
●DIN rail installation.
