1SDA071624R1 ABB E2.2N 1600 Ekip Touch LI 4p FHR Air Circuit Breaker

Why Choose the ABB E2.2N 1600 Ekip Touch LI 4p FHR Air Circuit Breaker?

The ABB E2.2N 1600 Ekip Touch LI 4p FHR, order code 1SDA071624R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for dependable protection and switching in demanding low-voltage power distribution systems. Its E2.2N frame combines a 1600 A current rating with the advanced Ekip Touch LI solid-state electronic trip unit.

The Ekip Touch LI release provides long-time overload and instantaneous short-circuit protection, combining essential circuit protection with ABB's touchscreen-based Ekip interface. The breaker is supplied as a fixed four-pole unit with rear horizontal terminals, four auxiliary contacts and breaker open/closed position indication.

The E2.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA throughout the principal 400–690 V AC range, with service breaking capacity equal to 100% of Icu and a rated short-time withstand current of 66 kA for 1 s. These characteristics make the 1SDA071624R1 a robust solution for industrial, commercial and infrastructure distribution switchboards.
