The AP902 arc flash protective relay is designed to quickly detect and clear arc flash incidents in low-voltage (LV) and medium-voltage (MV) electrical networks. AP902 limits damages to equipment, improve safety, avoid and protect personnel injuries.

The AP902 arc flash protective relay can be used as a stand-alone arc protection relay or applied in more complex switchgear layouts.

The AP902 arc flash protective relay is designed for the protection of all types of Industrial, Railway, Generation and Distribution networks.
