A Surge Protective Device (SPD), also known as a surge suppressor or lightning arrester, is an essential electrical safety component designed to protect electronic equipment and power systems from transient voltage spikes caused by lightning strikes, power grid fluctuations, or electrostatic discharges. By diverting excess voltage to the grounding system, SPDs limit overvoltage to safe levels, preventing damage to sensitive devices such as computers, industrial machinery, telecommunications systems, and household appliances.
