ABB XT4LU3150AFJ000XXX Industrial Relay Module

ABB XT4LU3150AFJ000XXX is a molded‑case circuit breaker (MCCB) in ABB’s XT4 family, designed to deliver reliable overcurrent protection in industrial low‑voltage power distribution panels and control cabinets, where compact form, predictable tripping behavior, and robust short‑circuit interruption are essential for safeguarding feeders, motors, and downstream equipment. Its LU3150A configuration indicates an L‑type trip unit with a short‑circuit rating of 50 kA, and the AFF000XXX suffix specifies this exact model variant within ABB’s XT4 LU lineup, enabling precise selection for systems requiring calibrated protection with strong fault isolation characteristics. The XT4 family is engineered for modularity and quick field replacement, aligning with standard panelboard architectures and ABB’s mounting footprints, while offering clear labeling and consistent performance across temperature ranges and electrical environments common in manufacturing facilities and process plants. This exact part number, XT4LU3150AFJ000XXX, differentiates this model from other XT4 LU configurations (such as NU, SU, HU, or XU variants) and communicates its specific trip characteristics and interruption capacity within ABB’s product catalog, helping you source the precise device for your protective scheme.
