Common Myths About How Surge Protector Works

There are many myths and misconceptions about how a surge protector works, which can lead to improper use and inadequate protection. Understanding these myths and the actual way surge protectors work will help you make informed decisions about protecting your electrical equipment. Debunking these myths ensures you get the most out of your surge protector and avoid costly mistakes.

One common myth is that surge protectors work indefinitely. In reality, surge protectors have a limited lifespan and can only handle a certain number of surges before their components degrade. Each time a surge protector diverts a surge, its MOVs and GDTs wear down, and eventually, the device will no longer provide protection. This is why it’s important to replace surge protectors every 3-5 years or after a major surge.

SWGCT surge protector includes indicator lights that alert users when the device is no longer functional, making it easy to know when to replace it. This feature ensures you always have reliable protection, debunking the myth that surge protectors last forever.

Another myth is that surge protectors protect against all types of power issues. While surge protectors work well against voltage surges, they do not protect against brownouts (low voltage) or blackouts (no voltage). Brownouts and blackouts require a backup generator or UPS (Uninterruptible Power Supply), not a surge protector.

SWGCT SPD is designed specifically for surge protection, and SWGCT also offers ATS and generator solutions for brownout and blackout protection. Understanding the difference ensures you have the right protection for all power issues, not just surges.
