1SDA104353R1 ABB E2.2H/E9 2000 Ekip Dip LSIG 3p FHR 900V

Why Choose the ABB E2.2H/E9 2000 Ekip Dip LSIG 3p FHR 900V?

The ABB E2.2H/E9 2000 Ekip Dip LSIG 3p FHR 900V, order code 1SDA104353R1, is a SACE Emax 2/E9 fixed air circuit breaker engineered for demanding AC power-distribution systems. It combines the E2.2 frame and high-performance H breaking-capacity level with a 2000 A rated uninterrupted current, three-pole construction and ABB's Ekip Dip electronic trip unit.

Its Ekip Dip LSIG protection release provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. This combination provides comprehensive electronic protection against the principal overcurrent and earth-fault conditions encountered in industrial power-distribution networks.

Designed for 900 V AC applications, the 1SDA104353R1 provides an ultimate and service short-circuit breaking capacity of 65 kA at 900 V AC. The fixed breaker uses rear flat horizontal terminals, making it a robust solution for high-current switchboards where compact installation, high breaking performance and LSIG protection are required.

High-Performance Protection for 900 V AC Distribution

The ABB SACE Emax 2/E9 platform is designed for AC power systems operating above conventional 690 V distribution levels. The E2.2H/E9 combines a 2000 A current rating with 65 kA Icu and Ics at 900 V AC, giving the breaker substantial interruption capability for demanding industrial and infrastructure networks.

The Ekip Dip LSIG release provides coordinated electronic protection against sustained overloads, delayed and instantaneous short circuits, and earth faults. Together with a 65 kA short-time withstand rating, rear horizontal connections and fixed construction, the 1SDA104353R1 provides a strong foundation for appropriately engineered high-current distribution assemblies.
