The Allen-Bradley 1409-FOBD Arcing Ground Fault Detection Relay protects motor circuits from arc-to-ground faults with a 1–6 A ground-fault protection range and a 460 VAC supply. It provides a Form C output contact, a fixed 50 ms trip delay, and an integrated test circuit to verify proper operation. As part of the 1409 Arcing Ground Fault Detection System family, FOBD is designed for Class II systems with high current inhibit, delivering targeted arc fault detection in industrial environments.
