A surge protection device (SPD) is an electrical safety component used to divert dangerous overvoltage and lightning-induced surges to the ground. It limits voltage to a safe level and protects electrical equipment, circuits, and systems from surge damage.

A circuit breaker protects against overcurrent and short circuits. A surge protector (SPD) protects against overvoltage and transient surges such as lightning. They serve different protective functions and are often used together for complete safety.

When abnormal overvoltage or surge occurs, the SPD quickly changes its internal impedance to a low-resistance state, diverting surge current to the grounding system. It clamps the voltage to a safe level and then automatically resets to normal status.
