1SDA101168R1 ABB XT7S 1250 Ekip Dip LIG 1250 A 4-Pole Circuit Breaker

Why Choose the ABB XT7S 1250 Ekip Dip LIG 1SDA101168R1 Circuit Breaker?

The ABB XT7S 1250 Ekip Dip LIG 1SDA101168R1 is a high-performance moulded-case circuit breaker (MCCB) from the ABB SACE Tmax XT series, designed for demanding low-voltage power distribution and equipment protection. Combining a 1250 A rated current with a four-pole configuration, it provides dependable high-current circuit protection for industrial, commercial and infrastructure electrical systems.

Equipped with an Ekip Dip LIG electronic trip unit, the breaker provides long-time overload, instantaneous short-circuit and ground-fault protection. This LIG protection architecture helps safeguard cables, busbars, transformers, generators, switchgear and connected equipment against damaging electrical faults while supporting coordinated protection within low-voltage distribution networks.

The 1SDA101168R1 is supplied as a fixed four-pole circuit breaker with front terminals. The XT7S version provides an S-class 50 kA ultimate and service short-circuit breaking capacity at 415 V AC, combining substantial fault interruption performance with a robust 1250 A current rating for demanding switchboard applications.
