Why Choose the ABB 1SDA104327R1 Emax 2 E2.2S/E9 2500 Ekip Dip LSI 3-Pole FHR 900 V?
The ABB 1SDA104327R1 is a SACE Emax 2 E2.2S/E9 air circuit breaker rated at 2500 A and 900 V AC. This three-pole fixed configuration combines the E2.2S frame with an Ekip Dip LSI electronic trip unit and fixed horizontal rear terminals for demanding high-current power distribution applications.
The Ekip Dip LSI electronic release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. The breaker has adjustable overload protection from 1000–2500 A, short-time delayed short-circuit protection from 1500–25000 A and instantaneous short-circuit protection from 3750–37500 A.
The E2.2S/E9 configuration provides a rated ultimate short-circuit breaking capacity of 50 kA at 900 V AC, together with a rated service short-circuit breaking capacity of 50 kA. Its fixed horizontal rear (FHR) main connections are designed for integration into compatible low-voltage switchboards where rear busbar or conductor connections are required.

LSI Protection for 900 V Power Distribution
The Ekip Dip LSI release provides three principal overcurrent protection functions. Long-time protection responds to sustained overload conditions, short-time protection provides a controlled response to high fault currents where coordination with downstream protective devices is required, and instantaneous protection provides rapid interruption of severe short circuits.
Combined with the E2.2S/E9 2500 A breaker platform, 50 kA short-circuit performance at 900 V AC and fixed horizontal rear terminals, these protection functions make the 1SDA104327R1 suitable for high-current switchboards where dependable feeder or incomer protection and rear-connected busbar integration are required.
Typical Applications
- High-current low-voltage switchboards.
- 900 V AC power distribution systems.
- Industrial power distribution networks.
- Main incomer and feeder protection.
- Transformer secondary distribution.
- Industrial plants and process facilities.
- Fixed switchgear assemblies with rear busbar connections.
- Three-phase systems requiring adjustable LSI overcurrent protection.
