Applications & Use Cases

The E2.2N 2500 Ekip Dip LSI 3p F HR (ABB 1SDA071062R1) is designed for main and sub-main power distribution switchboards in industrial facilities, commercial buildings, data centres, and infrastructure projects. Its high breaking capacity of 66 kA makes it suitable for protection of large transformers, standby generators, and incomer/feeder circuits in high-fault-level installations. The Ekip Dip LSI tripping unit provides field-adjustable overload (L), short-circuit (S), and instantaneous (I) protection thresholds, supporting coordination with downstream MCCBs and MCBs. The fixed (F) mounting configuration ensures a robust, permanent installation in main distribution panels and motor control centres (MCCs).
