Surge Protection Devices (SPDs) are designed to protect electrical and electronic equipment from transient surge conditions, such as voltage spikes and surges caused by lightning, power anomalies, or other electrical disturbances. These devices work by limiting the voltage supplied to an electric device by either blocking or redirecting the surge current to the ground, thus preventing damage to the equipment, and ensuring its safety.

SPDs are commonly used in residential, commercial, and industrial applications to protect sensitive equipment such as computers, telecommunication systems, and medical equipment. They are typically installed at the main electrical panel or at the point of use to provide protection against voltage surges.
