1SDA071868R1 ABB E6.2H 4000 Ekip Hi-Touch LSI 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2H 4000 Ekip Hi-Touch LSI 4p FHR Air Circuit Breaker?

The ABB E6.2H 4000 Ekip Hi-Touch LSI 4p FHR, order code 1SDA071868R1, 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 E6.2 series, this fixed breaker combines a 4000 A rated uninterrupted current with the advanced Ekip Hi-Touch LSI electronic trip unit.

The E6.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC together with a rated short-time withstand current of 100 kA for 1 s. Its Ekip Hi-Touch LSI trip unit provides long-time overload, selective short-time and instantaneous short-circuit protection, supporting effective discrimination and coordination throughout complex electrical distribution networks.

This version is a four-pole fixed air circuit breaker with rear horizontal (FHR) connections. The combination of the high-current E6.2 frame, H-level fault performance and sophisticated Ekip Hi-Touch protection platform makes the 1SDA071868R1 particularly suitable for main switchboards, industrial plants, data centres and critical infrastructure where dependable fault interruption and advanced electrical supervision are required.
