Why Choose the ABB E2.2S 2500 Ekip Touch LSI 3p WMP Air Circuit Breaker?
The ABB E2.2S 2500 Ekip Touch LSI 3p WMP, order code 1SDA072425R1, is a high-performance three-pole air circuit breaker (ACB) moving part from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage electrical distribution systems. Combining the E2.2S frame with a 2500 A rated uninterrupted current and ABB's Ekip Touch LSI electronic trip unit, it provides configurable overload and short-circuit protection for high-current industrial, commercial and infrastructure power networks.
This breaker uses a withdrawable construction for integration with a compatible Emax 2 fixed part, supporting efficient inspection, servicing and replacement within switchboard installations. Its Ekip Touch LSI solid-state electronic release provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection, while the Touch interface supports straightforward configuration and supervision of the protection functions.
The E2.2S 2500 delivers an ultimate short-circuit breaking capacity of 85 kA at 400/415 V AC and 66 kA at 690 V AC, with a rated short-time withstand current of 66 kA for 1 s. Its combination of a 2500 A current rating, three-pole configuration, high short-circuit performance and withdrawable moving-part construction makes the 1SDA072425R1 particularly suitable for main distribution, incomer and high-current feeder applications.

Advanced LSI Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage electrical networks by detecting and interrupting overload and short-circuit conditions before they can damage cables, busbars, switchgear or connected equipment. The E2.2S 2500 combines a substantial 2500 A current rating with 85 kA Icu at 400/415 V AC and 66 kA Icw for 1 s, making it particularly suitable for demanding main distribution and high-current feeder applications.
The Ekip Touch LSI electronic trip unit provides long-time overload protection, short-time selective short-circuit protection and instantaneous short-circuit protection. The short-time function enables intentional coordination with downstream protective devices, helping improve selectivity and continuity of supply while retaining fast instantaneous protection against severe fault currents.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plants.
- Commercial building electrical distribution.
- Data centres and critical power infrastructure.
- Utility and infrastructure switchgear.
- Transformer and generator distribution systems.
- High-current incomer and feeder protection.
