1SDA100875R1 ABB XT7S 1000 Ekip G Touch LSIG 1000A 3-Pole Circuit Breaker

Why Choose the ABB 1SDA100875R1 XT7S 1000 Circuit Breaker?

The ABB 1SDA100875R1, type XT7S 1000 Ekip G Touch LSIG In1000 3p FF, is a high-performance moulded case circuit breaker (MCCB) for generator and electrical system protection designed for demanding low-voltage installations. As part of the advanced ABB SACE Tmax XT range, it combines a 1000 A rated uninterrupted current with an Ekip G Touch LSIG solid-state electronic trip unit for comprehensive protection of generators, conductors and associated distribution circuits.

The Ekip G Touch LSIG electronic release provides long-time, short-time, instantaneous and earth-fault protection functions, allowing the protection characteristics to be configured for demanding generator and power distribution applications. Its advanced touch-interface platform supports straightforward configuration and monitoring, while the fixed three-pole construction with front terminals enables integration into generator switchboards and industrial electrical assemblies.

With a rated uninterrupted current of 1000 A, a rated operational voltage of up to 690 V AC and an XT7S 50 kA performance class, the 1SDA100875R1 provides robust protection for high-power electrical installations. The breaker is supplied as a complete fixed device with a protection unit, front main-circuit connections and provision for an optional motor operator.

Advanced Generator Protection for Industrial Power Systems

Generator circuits require carefully coordinated protection because their available fault currents and operating characteristics can differ from conventional utility-fed distribution systems. The ABB Ekip G Touch LSIG electronic release provides configurable long-time, short-time, instantaneous and earth-fault protection functions, helping protect generators, conductors and connected equipment against overloads, short circuits and earth faults.

The SACE Tmax XT platform combines electronic protection, flexible connectivity and robust switching performance in a compact industrial circuit breaker. The XT7S 1000 is therefore well suited to generator switchboards, standby power installations, industrial distribution systems and critical-power applications where dependable protection, isolation and flexible configuration are required.

Typical Applications

• Industrial generator protection systems.
• Standby and emergency power generation.
• Generator control and distribution switchboards.
• Commercial and industrial backup power systems.
• Combined heat and power installations.
• Critical power and infrastructure systems.
• High-current industrial low-voltage distribution.
