ABB XT4H250-3P-150A-600V-120V Circuit Breaker

ABB SACE Tmax XT4H250-3P-150A-600V-120V is a three‑pole molded‑case circuit breaker (MCCB) on the XT4H250 frame, rated for 150 A and designed for voltages up to 600 V, UL/CSA listed for standard industrial distribution. It is a fixed three‑pole unit with front terminals and, in common XT4H configurations, uses a thermomagnetic release (TMA) or LS/I trip unit; ABB catalogs show XT4H250 as UL/CSA listed and compatible with front-terminal mounting. The XT4H family supports remote control options such as shunt release (120 V) and undervoltage release; the 120 V shunt configuration is indicated in Tmax XT data and accessories documentation. ABB’s official XT4 product pages confirm the 250 A frame and 600 V maximum rating, positioning XT4H250‑3P‑150A‑600V‑120V for industrial distribution, motor control, and compact panel installations.
