The ABB XT7H 800 Ekip G Hi-Touch LSIG 1SDA100942R1 is a high-performance moulded-case circuit breaker (MCCB) designed for advanced generator and low-voltage power-distribution protection. As part of the ABB SACE Tmax XT series, this XT7 circuit breaker combines an 800 A rated current, high short-circuit interruption capability and sophisticated electronic protection for demanding industrial, commercial and infrastructure electrical systems.
Equipped with an Ekip G Hi-Touch LSIG electronic trip unit, the breaker provides an advanced protection platform developed for generator and power-distribution applications. Its LSIG architecture provides long-time, short-time, instantaneous and ground-fault protection functions, while the Hi-Touch platform adds sophisticated protection, measurement and system-management capabilities for modern electrical networks.
With a rated current of 800 A, a three-pole configuration and the XT7H 70 kA breaking-capacity class, the 1SDA100942R1 is supplied in a fixed configuration with front terminals. This combination of high breaking performance, generator-focused protection and advanced electronic functionality makes it particularly suitable for generator switchboards, main distribution assemblies and critical industrial power systems.
Moulded-case circuit breakers such as the ABB Tmax XT7 protect electrical systems by interrupting current when abnormal operating conditions exceed configured protection thresholds. Electronic releases provide precise control over protection characteristics, helping safeguard generators, conductors, busbars, switchgear and connected equipment while enabling effective coordination across complex electrical networks.
The Ekip G Hi-Touch platform is particularly suited to sophisticated generator protection and power-management applications. Combined with the LSIG protection architecture and the high-breaking-capacity XT7H platform, the 1SDA100942R1 provides a powerful solution for installations requiring advanced electronic protection, system selectivity and dependable continuity of service.
