ABB SACE Tmax XT4N 250 4-Pole Molded Case Circuit Breaker (225A - 2250A, Fully Rated Neutral)

Achieve ultimate flexibility and robust fault protection with the ABB SACE Tmax XT4N 250. This heavy-duty 4-pole Molded Case Circuit Breaker (MCCB) features an adjustable thermomagnetic release (TMA) rated at 225A and a Fully Rated Neutral (InN=100%), making it ideal for modern electrical systems with high harmonic loads.

Unlike standard breakers, this unit offers an adjustable instantaneous short-circuit setting (1125A - 2250A), allowing you to prevent nuisance tripping from motor inrush currents while maintaining high safety standards.

Built on the robust XT4N frame, this breaker provides a reliable breaking capacity for commercial and industrial power distribution systems. It offers excellent versatility with a rated operational voltage of up to 690V AC and an impressive 750V DC, making it an ideal choice for protecting large motors, main feeders, and primary distribution panels.

Engineered for longevity, it delivers a mechanical lifespan of 25,000 cycles and an electrical lifespan of 8,000 cycles. With front bolt terminals designed for large busbars ranging from 85 to 200 mm², installation is secure, straightforward, and built for high-current applications. The 4-pole configuration with 100% rated neutral ensures full protection for both phase and neutral lines.
