The ABB E2.2H 2500 Ekip G Touch LSIG 3p WMP, order code 1SDA072437R1, 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 power distribution and generator applications. Combining the E2.2H frame with a 2500 A rated uninterrupted current and ABB's Ekip G Touch LSIG electronic trip unit, it provides comprehensive protection for critical industrial, commercial and infrastructure electrical 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 G Touch LSIG solid-state electronic release combines long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection with generator-oriented protection functionality and a touch interface for configuration and supervision.
The E2.2H 2500 delivers an ultimate short-circuit breaking capacity of 100 kA at 400/415 V AC and 85 kA at 690 V AC, together with a rated short-time withstand current of 85 kA for 1 s. Its 2500 A current rating, three-pole configuration, integrated ground-fault protection and withdrawable moving-part construction make the 1SDA072437R1 particularly suitable for generator switchboards, main distribution, incomers and high-current feeder applications.
Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage electrical networks by detecting and interrupting overload, short-circuit and ground-fault conditions before they can damage generators, cables, busbars, switchgear or connected equipment. The E2.2H 2500 combines a substantial 2500 A current rating with 100 kA Icu at 400/415 V AC and 85 kA Icw for 1 s, providing substantial fault-current performance for demanding power distribution and generation systems.
The Ekip G Touch LSIG electronic trip unit combines generator-oriented functionality with long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection. This comprehensive protection platform supports coordinated protection throughout complex low-voltage networks while providing the functionality required for applications involving generators and critical distribution equipment.
