1SDA071536R1 ABB E2.2S 800 Ekip Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E2.2S 800 Ekip Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E2.2S 800 Ekip Touch LSIG 4p FHR, order code 1SDA071536R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, control and switching in demanding low-voltage power distribution systems. Its E2.2S frame combines substantial short-circuit performance with the advanced Ekip Touch LSIG electronic trip unit.

Rated at 800 A, this breaker is supplied in a fixed configuration with rear horizontal terminals. The Ekip Touch LSIG solid-state release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, while its touchscreen interface supports intuitive configuration, measurement and system monitoring.

The E2.2S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 440 V AC and a rated short-time withstand current of 66 kA for 1 s. This combination of high fault performance, advanced electronic protection and flexible connectivity makes the 1SDA071536R1 well suited to critical industrial, commercial and infrastructure distribution systems.
