ABB SACE Tmax XT5S 400 Ekip M Dip I Circuit Breaker (400A, 3-Pole, Motor Protection)

Ensure precise short-circuit protection for your motor circuits with the ABB SACE Tmax XT5S 400 Ekip M Dip I. This heavy-duty 3-pole Molded Case Circuit Breaker (MCCB) is rated at the maximum frame capacity of 400A and features an Ekip M Dip I electronic trip unit, providing instantaneous (short-circuit) protection only—ideal for motor protection applications where overload protection is handled separately.

Unlike standard breakers, the Ekip M Dip I trip unit focuses purely on magnetic (short-circuit) protection, allowing for precise coordination with separate thermal overload relays in motor starter assemblies. This makes it an ideal choice for protecting large motors and distribution feeders in demanding industrial environments.

Built on the robust XT5S 400 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 3-pole configuration is ideal for standard three-phase loads. With a low power loss of 19 W per pole, it is also highly energy-efficient.
