An AC Power Surge Protection Device (SPD), also known as a surge suppressor or surge protector, is a critical component in safeguarding electrical systems and devices from voltage spikes. These spikes can occur due to various reasons, including lightning strikes, power outages, and sudden changes in power demand. The primary function of an ac power surge protection device is to protect sensitive electronic equipment by limiting transient overvoltages and diverting surge current away from the protected load, thereby preventing damage and prolonging the lifespan of electrical devices. AC Power SPDs are designed to be installed in residential, commercial, and industrial settings, where they serve as the first line of defense against electrical surges that can cause not only equipment failure but also pose a fire risk. By offering a path of least resistance to ground or neutral, these devices ensure that excess voltage is safely discharged, thus maintaining the integrity of the electrical system.
