1SDA072438R1 ABB E2.2H 2500 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 2500 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker?

The ABB E2.2H 2500 Ekip Hi-Touch LSI 3p WMP, order code 1SDA072438R1, is a high-performance three-pole air circuit breaker (ACB) moving part from the ABB SACE Emax 2 range, engineered for protection and switching in demanding low-voltage electrical distribution systems. Combining the E2.2H frame with a 2500 A rated uninterrupted current and ABB's advanced Ekip Hi-Touch LSI electronic trip unit, it provides sophisticated overload and short-circuit protection for industrial, commercial and critical 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 Hi-Touch LSI solid-state electronic release provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection, complemented by the advanced measurement, monitoring and supervision capabilities of the Hi-Touch platform.

The E2.2H 2500 delivers an ultimate short-circuit breaking capacity of 100 kA at 400/415 V AC, while its long-time overload setting is adjustable from 1000–2500 A, short-time protection from 1500–25000 A and instantaneous protection from 3750–37500 A. Its high fault-current capability, 2500 A current rating, three-pole configuration and withdrawable moving-part construction make the 1SDA072438R1 particularly suitable for main distribution, incomer and high-current feeder applications.

Advanced Hi-Touch LSI Protection and Monitoring

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 E2.2H 2500 combines a substantial 2500 A current rating with 100 kA ultimate short-circuit breaking capacity at 400/415 V AC, providing substantial fault-current interruption capability for demanding main distribution and high-current feeder applications.

The Ekip Hi-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 supports coordination with downstream protective devices, while the Hi-Touch platform adds advanced measurement and monitoring capabilities for supervision and management of critical low-voltage power distribution systems.

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.
