Why Choose the ABB E2.2H/E9 1250 Ekip Dip LSIG 3p FHR 900V?
The ABB E2.2H/E9 1250 Ekip Dip LSIG 3p FHR 900V, order code 1SDA104348R1, 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 three-pole breaker combines a rated uninterrupted current of 1250 A with ABB's Ekip Dip LSIG electronic protection release.
The Ekip Dip LSIG trip unit provides electronic protection covering long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground or earth-fault (G) functions. This combination provides comprehensive protection against common distribution-system faults while retaining the straightforward configuration associated with ABB's Ekip Dip platform.
This E2.2H/E9 configuration is designed for 900 V AC applications and features a fixed three-pole construction with horizontal rear terminals (FHR). The H performance level provides a rated ultimate short-circuit breaking capacity of 65 kA at 900 V AC, making the breaker particularly suitable for installations with high prospective fault currents.
