There are various types of surge protectors available on the market, each offering different options and levels of protection. Whether you’re looking for a power strip surge protector, a wall-mounted surge protector, or a whole-house surge protector, it’s important to also consider factors like the number of outlets, the type(s) of outlets needed, the level of protection, safety features, and additional functionalities when making your selection.

How Surge Protectors Work

Surge protectors are essential devices that safeguard your valuable electronics from voltage spikes and surges. But, have you ever wondered how surge protectors actually work? Understanding their inner workings will help you make an informed decision when choosing the right surge protector for your needs.

Surge protectors use a component called a metal oxide varistor (MOV) to detect and redirect excess voltage to the ground wire before it reaches your devices. The MOV allows normal current to pass through while diverting harmful surges through the ground wire. This process prevents the surges from damaging your connected devices by ensuring they receive only the appropriate voltage.

It’s important to note that surge protectors are different from power strips, which only provide additional power outlets. Surge protectors offer an added layer of protection against voltage fluctuations, ensuring the safety of your electronics. Some surge protectors even come with advanced features like fireproof technology and safe-fail protection.

Additional Features and Considerations

• Fireproof technology: Certain surge protectors are equipped with materials that can resist and prevent fires caused by electrical faults.
• Safe-fail protection: In the event of a power surge that exceeds the maximum protection capacity of the surge protector, safe-fail protection shuts down the surge protector, ensuring that no further voltage is allowed to pass through.
• Joules of protection: Surge protectors are assigned a joule rating, which indicates their maximum ability to absorb energy from surges. The higher the joule rating, the more energy the surge protector can handle without compromising its protective abilities.

Remember, when selecting a surge protector, it’s important to consider not only the level of protection it provides but also any additional features that may enhance its effectiveness and safety.

Now that you have a clear understanding of how surge protectors work and the additional features they offer, you can confidently choose the right surge protector to safeguard your valuable devices.
