AFR arc flash protective relay is a costeffective solution that reduces arc-fault damage by detecting the light from an arc flash and rapidly tripping in low-voltage (LV) and medium-voltage (MV) electrical networks. three remote light sensors can be connected to one relay.

It used to limits damages to equipment, improve safety, avoid and protect personnel injuries. It's also can be used as a stand-alone arc protection relay or applied in more complex switchgear layouts.
