1SDA104372R1 ABB E2.2H/E9 2500 Ekip Dip LSI 4p FHR 900V Air Circuit Breaker

Why Choose the ABB E2.2H/E9 2500 Ekip Dip LSI 4p FHR 900V?

The ABB E2.2H/E9 2500 Ekip Dip LSI 4p FHR 900V, order code 1SDA104372R1, is a high-performance SACE Emax 2 air circuit breaker designed for switching and protection in demanding low-voltage AC power distribution systems. Built on the E2.2 frame, this fixed four-pole breaker combines a rated uninterrupted current of 2500 A with ABB's Ekip Dip LSI electronic protection release.

The Ekip Dip LSI trip unit provides electronic protection covering long-time overload (L), short-time selective protection (S) and instantaneous short-circuit protection (I). The long-time protection setting can be adjusted from 0.4–1 × In, while the Ekip Dip platform provides straightforward protection configuration for high-current distribution circuits.

This E2.2H/E9 configuration is designed for 900 V AC applications and features a fixed four-pole construction with horizontal rear terminals (FHR). Its H performance level provides a rated ultimate short-circuit breaking capacity of 65 kA, while the four-pole arrangement supports three-phase distribution systems where switching of the neutral conductor is required.
