ABB XT4HU3250MFF000XXX Molded Case Circuit Breaker

ABB Tmax XT4HU3250MFF000XXX is a three-pole molded‑case motor circuit protector (MCP) in ABB’s XT4H family, built on a 250 A frame with front terminals (F) and an MA trip unit. This UL 80% rated variant (U) is intended for 600 V AC motor circuits, delivering thermal‑magnetic overload protection and automatic disconnection when fault current exceeds the trip setting. With a 250 A rated current and short‑circuit rating up to 150 kA at 600 V, it provides robust protection for demanding motor feeders in industrial environments. Designed for motor control centers and panel installations, XT4HU3250MFF000XXX protects motors in conveyors, pumps, fans, and processing lines, while integrating with ABB's Tmax XT ecosystem for coordinated protection and easy replacement within established electrical distributions.
