ABB REF615E_1G H-B-F-N-AE-AG-A-N-B-1-A-N-A-1-1G is an enhanced numerical feeder protection and control IED in ABB’s Relion® 615 series, built for medium‑voltage (6–35kV) distribution networks in utility, industrial, and renewable energy applications.

This model provides full feeder protection: three‑stage overcurrent (50/51, DT/IDMT), two‑stage earth fault (50N/51N), directional protection, voltage/frequency supervision, breaker failure, and thermal overload. It includes 16 digital inputs / 10 digital outputs and AE/AG analog configuration (3Is+6Us, 7I+3U+Io), supporting 1A/5A CTs or Rogowski coils.

Communication features IEC 61850 Ed1/2 (with HSR/PRP redundancy) and Modbus RTU/TCP, plus a front USB port for PCM600 configuration and fault data logging. The withdrawable unit design simplifies maintenance, while the universal power supply (24–250VDC/100–240VAC) and wide temperature range (−20°C to +60°C) ensure reliability in harsh environments.
