1SDA101124R1 ABB XT7S 1250 Ekip Dip LSIG 1250 A 4-Pole Circuit Breaker

Why Choose the ABB XT7S 1250 Ekip Dip LSIG 1SDA101124R1 Circuit Breaker?

The ABB XT7S 1250 Ekip Dip LSIG 1SDA101124R1 is a high-performance moulded-case circuit breaker (MCCB) from the ABB SACE Tmax XT series, engineered for dependable low-voltage power distribution and circuit protection. Combining a 1250 A rated current with a four-pole configuration, it is designed for demanding three-phase systems where switching and protection of the neutral conductor are required.

Equipped with an Ekip Dip LSIG solid-state electronic trip unit, the breaker provides long-time, short-time, instantaneous and ground-fault protection. This comprehensive LSIG architecture helps protect cables, busbars, transformers, switchgear and connected equipment against overload, short-circuit and earth-fault conditions while supporting effective protection coordination throughout the electrical distribution system.

The 1SDA101124R1 is supplied as a fixed four-pole circuit breaker with front terminals and a lever operating mechanism. As an XT7S model, it belongs to ABB's S interruption-performance class and combines high-current protection with the flexibility of the XT7 frame for industrial, commercial and infrastructure switchboards.
