1SDA101157R1 ABB XT7S 1600 Ekip G Touch LSIG In1600 4p FF Circuit Breaker

Why Choose the ABB XT7S 1600 Ekip G Touch LSIG In1600 4p FF Circuit Breaker?

The ABB XT7S 1600 Ekip G Touch LSIG In1600 4p FF, order code 1SDA101157R1, is a high-performance four-pole moulded case circuit breaker (MCCB) designed for generator protection and demanding low-voltage electrical distribution systems. Part of the ABB SACE Tmax XT series, it combines a 1600 A rated uninterrupted current with the advanced Ekip G Touch LSIG electronic trip unit.

The Ekip G Touch LSIG solid-state release provides long-time, short-time, instantaneous and ground-fault protection functions, delivering comprehensive electronic protection for generator-fed and industrial electrical networks. Adjustable protection settings allow the circuit breaker to be coordinated with generators, cables, switchgear and downstream equipment while providing effective protection against overload and short-circuit conditions.

The XT7S version provides a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC, 50 Hz. Its four-pole, fixed configuration with front terminals and lever operating mechanism makes the 1SDA101157R1 a robust solution for generator switchboards, industrial distribution boards and other high-current low-voltage assemblies.

Advanced LSIG Protection for Generator Applications

Generator-fed electrical systems require carefully coordinated protection because their operating and fault-current characteristics can differ from conventional utility-fed networks. The ABB Ekip G Touch LSIG trip unit provides long-time, short-time, instantaneous and ground-fault protection, giving the circuit breaker a comprehensive set of electronic protection functions for generators and associated electrical distribution equipment.

The XT7S platform combines this generator-focused electronic protection with robust high-current circuit breaker performance. With its 1600 A rating, four-pole construction, 690 V AC rated voltage and 50 kA Icu at 400 V AC, the 1SDA101157R1 is well suited to generator switchboards, standby power systems and demanding industrial power distribution applications.

Typical Applications

• Generator protection systems.
• Generator control and distribution switchboards.
• Standby and emergency power installations.
• Industrial low-voltage switchboards.
• Main and sub-main power distribution.
• Manufacturing and process plants.
• High-current generator feeders.
• Electrical systems requiring advanced LSIG electronic protection.
