The AP901S arc flash protective relay is designed to quickly detect and clear arc flash incidents in low-voltage (LV) and medium-voltage (MV) electrical networks. AP901S limits damages to equipment, improve safety, avoid and protect personnel injuries.

AP901S is the ideal detector for the protection of a double busbar thanks to its large number of binary inputs and outputs.

The AP901S arc flash protective relay can be used as a stand-alone arc protection relay or applied in more complex switchgear layouts.

The AP901S arc flash protective relay is designed for the protection of all types of Industrial, Railway, Generation and Distribution networks.
