What does a surge protector do?

A surge protector is designed to protect electronic devices from excess voltage that can occur during surge events, such as lightning strikes, power outages, or sudden increases in electrical load. It works by diverting or absorbing the excess voltage and preventing it from reaching the connected devices, thereby safeguarding the internal components from potential damage that high voltage can cause.

Surge protectors typically contain metal oxide varistors (MOVs) or other components that can react rapidly to high voltage levels, shunting the excess current away from sensitive equipment. This protection is crucial for preserving the functionality and longevity of devices such as computers, televisions, and home appliances. By ensuring that only safe levels of voltage pass through, surge protectors play a vital role in maintaining the integrity and safety of electrical systems and the devices connected to them.
