A surge protective device (SPD), also known as a surge suppressor or transient voltage surge suppressor (TVSS), is a device designed to protect electrical and electronic equipment from transient voltage surges or spikes. These surges are sudden, short-duration increases in voltage that can damage or destroy sensitive electronics.Think of it as a safety valve for your electrical system. Under normal conditions, it allows electricity to flow freely. However, when a dangerous surge occurs, the SPD quickly acts to divert the excess energy away from your valuable equipment, typically by shunting it safely to the ground wire.
