Why Choose the ABB 1SDA101128R1 XT7S 1250 Circuit Breaker?
The ABB 1SDA101128R1 is a high-performance four-pole moulded-case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Tmax XT7 range, this fixed circuit breaker combines a 1250 A rated current with an Ekip Touch LSI electronic trip unit for precise and configurable electrical protection.
The integrated Ekip Touch LSI solid-state electronic release provides long-time overload, selective short-time and instantaneous short-circuit protection functions. Its electronic protection technology supports accurate protection settings and effective coordination with other protective devices, making the XT7S suitable for industrial, commercial and infrastructure distribution systems.
The XT7S version provides a rated ultimate short-circuit breaking capacity of 50 kA at 400–415 V AC. The 1SDA101128R1 features a fixed four-pole construction with front terminals and a lever operating mechanism, providing protection and switching across all four poles for suitable three-phase distribution applications.
