1SDA100876R1 ABB XT7S 1250 Ekip G Touch LSIG 1250 A 3-Pole Circuit Breaker

Why Choose the ABB XT7S 1250 Ekip G Touch LSIG 1SDA100876R1 Circuit Breaker?

The ABB XT7S 1250 Ekip G Touch LSIG 1SDA100876R1 is a high-performance moulded-case circuit breaker (MCCB) designed for protection and control of generators and demanding low-voltage electrical distribution systems. As part of the advanced ABB SACE Tmax XT series, this XT7 circuit breaker combines a compact fixed configuration with sophisticated electronic protection for industrial, commercial and infrastructure applications.

Equipped with an Ekip G Touch LSIG electronic trip unit, the breaker provides long-time, short-time, instantaneous and ground-fault protection together with generator-oriented protection capabilities. The touch-enabled electronic release provides advanced monitoring and protection functionality, helping safeguard generators, cables, switchboards and connected equipment while supporting selective coordination and continuity of service.

With a rated current of 1250 A, a three-pole configuration and an ultimate short-circuit breaking capacity of 50 kA at 400–415 V AC, the 1SDA100876R1 is designed for fixed installation with front terminals and a lever operating mechanism. Its combination of high current capacity, generator-focused electronic protection and robust ABB Tmax XT construction makes it suitable for generator installations and major power-distribution feeders.

Advanced Generator and Power Distribution Protection

Moulded-case circuit breakers such as the ABB Tmax XT7 protect electrical systems by automatically interrupting current when abnormal operating conditions occur. The electronic trip system continuously monitors the circuit and initiates disconnection when configured protection thresholds are exceeded, helping prevent damage to generators, conductors, switchgear and connected equipment.

The Ekip G Touch family is specifically suited to generator protection and combines advanced electronic protection with the functionality required for modern generating installations. The LSIG protection package provides overload, selective short-circuit, instantaneous short-circuit and ground-fault protection, making the XT7S suitable for coordinated generator and low-voltage distribution networks.

Typical Applications

• Generator protection and generator control switchboards.
• Industrial power generation systems.
• Main and feeder protection in low-voltage switchboards.
• Commercial and infrastructure electrical installations.
• Emergency and standby power systems.
• Industrial plant electrical distribution.
• High-current power-distribution and switchgear assemblies.
