What is the difference between a surge arrester and a surge suppressor?

If you are confused by the uses of a Surge Suppressor, a Surge Arrester and a Lightning Arrester, you are definitely not alone. The differences between the 3 of them are similar but different at the same time.

All three of these have the same purpose, to keep unwanted electrical power from damaging your home and its systems. Whatever protects your home is definitely something that should be understood.

Surge Arrester
A surge arrester “arrests” unwanted power that enters your home from outside sources such as lightning, or surges from your power company. It sends that excess power directly into an installed grounding application.

Lightning Arrester
A lightning arrester “arrests” unwanted power from a lightning strike before it reaches your door and sends the power into the ground outside.

Surge Protector
A Surge Protector “protects” your home’s electrical system from power surges created inside your home. It is often intalled into the network in a whole home protection system.
