1SDA071698R1 ABB E2.2N 2500 Ekip Hi-Touch LSI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2N 2500 Ekip Hi-Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2N 2500 Ekip Hi-Touch LSI 4p FHR, order code 1SDA071698R1, 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 2500 A rated current with ABB's Ekip Hi-Touch LSI electronic trip unit and rear 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 electronic platform also incorporates Ekip Measuring Pro and Network Analyzer functionality, extending the breaker beyond circuit protection to provide integrated electrical measurement and power-quality analysis.

The E2.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA from 380–690 V AC. With a rated operational voltage of 690 V AC, 1000 V AC insulation voltage and four-pole fixed construction, the 1SDA071698R1 is well suited to main switchboards, transformer secondary distribution, industrial incomers and other high-current networks requiring advanced selective protection and monitoring.
