1SDA101672R1 ABB XT7S M 1250 Ekip Touch LSIG 1250A 4-Pole MCCB

Why Choose the ABB XT7S M 1250 Ekip Touch LSIG 1SDA101672R1 Circuit Breaker?

The ABB 1SDA101672R1, designated XT7S M 1250 Ekip Touch LSIG In1250 4p FF, is a high-performance four-pole moulded case circuit breaker (MCCB) designed for protection, switching and control of high-current low-voltage AC power distribution systems. As part of the advanced ABB SACE Tmax XT7 range, it combines a 1250 A rated current with an Ekip Touch electronic trip unit, high short-circuit breaking capacity and a stored-energy operating mechanism.

This fixed circuit breaker incorporates the ABB Ekip Touch LSIG electronic trip unit, providing long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. The electronic release provides configurable protection for demanding electrical distribution applications, while the XT7S performance level offers a rated ultimate short-circuit breaking capacity of 50 kA at 400–415 V AC.

With a rated uninterrupted current of 1250 A, four-pole construction, front terminals and a rated operational voltage of up to 690 V AC, the 1SDA101672R1 is ideal for industrial switchboards, main distribution panels, infrastructure and high-power electrical installations. Its fixed configuration and stored-energy operating mechanism support dependable operation within sophisticated power distribution systems.

Advanced Protection for High-Current Power Distribution

Moulded case circuit breakers such as the ABB Tmax XT7 protect electrical distribution systems against overloads, short circuits and other potentially damaging electrical faults while also providing reliable switching and isolation. The high breaking capacity of the XT7S enables substantial prospective fault currents to be safely interrupted before they can damage cables, switchgear or connected equipment.

The Ekip Touch LSIG trip unit extends this protection with configurable long-time, short-time, instantaneous and ground-fault functions. Combined with the XT7 platform's high current capability and stored-energy operating mechanism, this makes the 1SDA101672R1 particularly suitable for sophisticated industrial switchboards and critical low-voltage distribution systems.

Typical Applications

• Industrial low-voltage switchboards and distribution panels.
• Main incoming and feeder circuit protection.
• Manufacturing and process industry power distribution.
• Commercial and infrastructure electrical installations.
• Data centre and critical power distribution systems.
• Transformer and generator distribution circuits.
• Large machinery and plant electrical systems.
• Automated power distribution and switching systems.
