A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from lightning strikes, electrical system switching, or equipment malfunctions. SPDs work by diverting excess voltage to ground, preventing damage to sensitive equipment.
