Types of Surge Protectors

Below are some of the main types of surge protectors:

Basic Surge Protectors

As the name presents, a basic surge protector is a very straightforward model to get the job done. Their user-friendly design is intended to protect your RV from low or high spike of voltage so your circuitry isn’t suddenly fried. The reasons for these occurrences can be the result of unstable surges at RV parks or forces of nature such as lightning strikes.

Complete Surge Protectors

While basic surge protectors are a safe, general model, complete surge protectors are well-known for being a top of the line investments.

Despite their higher price tag, these models are worth the cost since they typically pay for themselves in the long-run, providing peace of mind should problems arise. As with basic protectors, complete surge protectors defend against low and high voltage, as well as high and low line frequency, open ground, and faulty wiring.
