ABB SACE Tmax XT5H 400 3-Pole Molded Case Circuit Breaker (320A)

Achieve ultimate flexibility and robust fault protection with the ABB SACE Tmax XT5H 400. This heavy-duty 3-pole Molded Case Circuit Breaker (MCCB) features an adjustable thermomagnetic release (TMA) rated at 320A, allowing you to precisely calibrate your protection to match your specific load requirements.

Unlike standard breakers, this unit offers an adjustable instantaneous short-circuit setting (1600A - 3200A), allowing you to fine-tune the magnetic trip to prevent nuisance tripping from large motor inrush currents while maintaining high safety standards.

Built on the robust XT5H frame, it offers exceptional breaking capacity and versatility. The unit provides 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 in demanding industrial, commercial, and renewable energy environments.

Engineered for longevity, it delivers a mechanical lifespan of 20,000 cycles and an electrical lifespan of 7,000 cycles. With front bolt terminals, installation is secure, straightforward, and built for high-current applications.
