1SDA071668R1 ABB E2.2N 2000 Ekip Hi-Touch LSI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2N 2000 Ekip Hi-Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2N 2000 Ekip Hi-Touch LSI 4p FHR, order code 1SDA071668R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for advanced protection, measurement and switching in demanding low-voltage power distribution systems. This fixed four-pole E2.2N configuration combines a 2000 A rated current with ABB's Ekip Hi-Touch LSI solid-state electronic trip unit and rear flat horizontal main terminals.

The Ekip Hi-Touch LSI release provides long-time overload (L), short-time selective short-circuit (S) and instantaneous short-circuit (I) protection. Its advanced platform incorporates Ekip Measuring Pro and Network Analyzer functionality, providing integrated electrical measurement and power-quality analysis alongside the breaker's primary protection functions.

The E2.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 400–690 V AC, with a rated short-time withstand current of 66 kA for 1 s and 50 kA for 3 s. With a rated operational voltage of 690 V AC, four-pole construction and fixed installation, the 1SDA071668R1 is well suited to main switchboards, transformer secondary systems, industrial incomers and critical high-current distribution networks.
