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. • Panel mounting design. • 3-phase current and earth-fault current measurement. • Informative display on LCD screen. • Less than 10 ms operation time (including the output relay). • Multiple passive DI point, indicate CB status. • Multiple trip contacts, free to configuration NC / NO status. • Programmable CB protect trip logic. • Optional extra monitor functions by RS-485 connection, user can customized. • Support OEM and add customized program for VCB control and protection logic.
