ABB XT1HU3030MFF000XXX Molded Case Circuit Breaker

ABB XT1HU3030MFF000XXX is a three‑pole Tmax XT molded‑case circuit breaker built for reliable motor protection in demanding industrial distributions. This 30 A, 3‑pole unit belongs to the XT1H family with an XT1 frame size rated up to 125 A and is listed for UL/CSA 600Y/347 V operation and IEC up to 690 V, making it suitable for mixed voltage systems. The device provides magnetic only (MCP) motor protection with a 25 kA interrupt rating at 600 V, helping to quickly clear motor faults while avoiding nuisance trips. Its front‑terminal configuration (top line side and bottom load side) uses front terminations (FF) with no lugs installed, allowing for convenient mounting and wiring in standard control panels. The module’s enclosure is designed for standard MCCB installation, and its compact XT1 housing measures about 5.12 in H x 3 in W x 2.75 in D, with operating temperatures from -13 to 158 degrees Fahrenheit, making it well suited for warm industrial environments. This specific part number corresponds to a fixed, UL/CSA‑listed MCCB suitable for motor circuits in 3‑phase networks, and is compatible with 600Y/347 V (UL/CSA) and 690 V (IEC) system voltages, ensuring broad interoperability across North American and international installations.
