Achieve ultimate flexibility and robust fault protection with the ABB SACE Tmax XT5N 630. This heavy-duty 4-pole Molded Case Circuit Breaker (MCCB) features an adjustable thermomagnetic release (TMA) rated at the maximum frame capacity of 630A 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 (3150A - 6300A), allowing you to prevent nuisance tripping from motor inrush currents while maintaining high safety standards.

Built on the robust XT5N 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 20,000 cycles and an electrical lifespan of 5,000 cycles. With front bolt terminals, 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.
