A surge protection device is designed to protect you and the electrical accessories within your home from electrical spikes.

How does it work?

A surge protection device SPD either blocks incoming voltage spikes or it directs the over voltage back down to earth.

How do I know if my SPD has been activated?

There are indicator windows located on the front of the SPD, if these turn RED it means there’s been a surge and the SPD module needs to be changed.
