ABB T4L250 Industrial Molded Case Circuit Breaker 3 Pole MCCB

ABB T4L250 molded-case circuit breaker (MCCB) is a three-pole protection device rated for 250 A with a maximum operating voltage of 600 V, designed to interrupt overloads and short circuits in industrial three‑phase feeders. This compact, industrial-grade MCCB is intended for use in power distribution panels, motor control centers, and machine safety circuits, providing reliable protection for wiring and equipment in harsh environments. The T4L250 is compatible with ABB SACE Tmax trip-unit families (such as PR221 and PR222 variants), enabling thermal-magnetic overcurrent protection with selectable characteristics and coordination with other protection devices in the installation. Its three‑pole configuration ensures balanced protection across all phases, supporting clean isolation and safe maintenance of downstream loads. Typical applications include feeders for motors, conveyors, pumps, and other heavy machinery in manufacturing and process facilities, where precise overcurrent protection and fast, predictable tripping are essential to minimize equipment damage and downtime.
