1SDA071880R1 ABB E6.2V 4000 Ekip G Hi-Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 4000 Ekip G Hi-Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2V 4000 Ekip G Hi-Touch LSIG 4p FHR, order code 1SDA071880R1, is a high-performance four-pole SACE Emax 2 air circuit breaker engineered for generator protection and demanding low-voltage power-distribution systems. Part of the ABB SACE Emax 2 E6.2 series, this fixed breaker combines a 4000 A rated uninterrupted current with the advanced Ekip G Hi-Touch LSIG electronic trip unit.

The E6.2V performance level delivers exceptional fault-interruption capability, with a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC and a rated short-time withstand current of 100 kA for 1 s. Its Ekip G Hi-Touch LSIG trip unit combines long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection with generator-oriented protection functions and advanced measurement capabilities.

This version is a four-pole fixed air circuit breaker equipped with rear horizontal (FHR) terminals. The combination of E6.2 construction, V-level breaking performance and the sophisticated Ekip G Hi-Touch platform makes the 1SDA071880R1 particularly suitable for generator switchboards, critical power systems, industrial plants and infrastructure where high prospective fault currents, selective coordination and detailed electrical supervision are required.

Advanced Generator Protection and Power-System Monitoring

Generator-fed electrical networks have protection requirements that differ from conventional utility-fed distribution systems. The ABB E6.2V combines a 4000 A rated uninterrupted current, 150 kA ultimate breaking capacity at 400 V AC and 100 kA short-time withstand capability for 1 s, providing a robust platform for high-power generator and distribution circuits exposed to demanding fault conditions.

The Ekip G Hi-Touch LSIG trip unit combines generator-oriented protection with advanced measurement, monitoring and power-quality analysis. Its LSIG architecture helps protect generators, cables, busbars, transformers and other critical equipment against overload, short-circuit and earth-fault conditions, while the Hi-Touch platform supports sophisticated supervision and integration within modern energy-management and automation systems.
