Why Choose the ABB E4.2V 4000 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E4.2V 4000 Ekip Hi-Touch LSIG 4p FHR, order code 1SDA071859R1, is a high-performance four-pole SACE Emax 2 air circuit breaker designed for protection, switching, measurement and supervision in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax 2 E4.2 series, this fixed breaker combines a 4000 A rated current with the advanced Ekip Hi-Touch LSIG electronic trip unit.

The E4.2V performance level provides exceptional fault-interruption capability, with a rated ultimate short-circuit breaking capacity of 150 kA and rated short-time withstand current of 100 kA. Its Ekip Hi-Touch LSIG trip unit provides long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection, supporting comprehensive protection and selective coordination throughout complex electrical distribution networks.

This version is a four-pole fixed air circuit breaker equipped with rear horizontal (FHR) terminals. The combination of high-current E4.2 construction, V-level breaking performance, integrated earth-fault protection and the sophisticated Ekip Hi-Touch platform makes the 1SDA071859R1 particularly suitable for major industrial switchboards, data centres, infrastructure and other critical power systems.
