ABB 56230179M Current Relay

ABB 56230179M Current Relay is an RXIG21 family overcurrent protection relay assembly from ABB/ASEA, designed for instantaneous or definite-time protection of feeders in protection schemes. It supports single-phase, two-phase, or three-phase configurations with medium-duty contacts and a hand-reset target, and is typically used with ABB timing modules (RXKE1, RXKF1) and auxiliary relays for signaling. The RXIG21 variant offers a current pickup range from 10 mA to 45 A, enabling precise pickup settings across protection zones; the RXIG21 family also supports multiple time-step configurations (definite-time protection with one time-step, 20 ms to 99 s) for coordinated protection in 50/60 Hz systems. This particular part is identified by 5623 0179-M (56230179M) and is used within RXIG-based assemblies for overcurrent and ground-fault protection in switchgear.
