A surge protection device is one of the primary components of electrical installation protection systems used in the electrical power supply networks, communication and telephone networks.  They are primarily the most efficient type of overvoltage protection. The surge protector limits the voltage supply to an electric device by blocking or shorting the excess voltage. The advantages of surge protection devices include the protection of low voltage distribution systems against direct ... Read more

Surge protection devices provide protection against voltage spikes and power surges. They shield electronics and electrical equipment from the damaging effects of surges or spikes that often occur in AC power lines and I/O ports. These devices prevent equipment damage by diverting damaging voltages or current to a safe ground. The need for surge protection devices has risen significantly owing to the increasing frequency of thunderstorms around the world which cause power surges.
