ABB SACE Tmax XT5S 400 4-Pole Molded Case Circuit Breaker (320A, Electronic Ekip Dip LSIG)

Achieve the ultimate in protection and coordination for your equipment with the ABB SACE Tmax XT5S 400. This heavy-duty 4-pole Molded Case Circuit Breaker (MCCB) features a state-of-the-art electronic trip unit (Ekip Dip LSIG), rated at 320A, providing precise overload (L), short-time (S), instantaneous (I), and ground-fault (G) protection in a single device.

Unlike standard thermomagnetic breakers, the Ekip Dip electronic trip unit allows for precise digital calibration of protection settings, eliminating nuisance tripping and ensuring optimal coordination with downstream devices. The LSIG protection provides the complete protection suite, making it an ideal choice for protecting main feeders, large motors, and primary distribution panels in demanding industrial environments.

Built on the robust XT5S frame, this breaker provides a high breaking capacity with an 85 kA service breaking capacity (Ics) at 220/230/240 V AC. It offers excellent versatility with a rated operational voltage of up to 690V AC, making it a reliable choice for modern power distribution systems.

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. The 4-pole configuration ensures full protection for both phase and neutral lines.
