Surge protection is a technology designed to protect electrical equipment from voltage spikes, or power surges. Lightning strikes, power outages, or electrical problems can cause voltage surges. These surges can damage or destroy electrical equipment such as computers, televisions, and other electronics. Surge protectors are designed to regulate voltage and protect connected equipment from any voltage surges. Surge protectors usually have a circuit breaker that cuts power when a voltage spike occurs to prevent damage to connected electrical equipment. Surge protectors are often used with power strips, and they provide an important layer of surge protection for your sensitive electronics.
