1SDA072336R1 ABB E2.2B 1600 Ekip Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2B 1600 Ekip Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2B 1600 Ekip Touch LSIG 3p WMP, order code 1SDA072336R1, 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 low-voltage electrical distribution systems. Combining the E2.2B frame with a 1600 A rated uninterrupted current and ABB's advanced Ekip Touch LSIG electronic trip unit, it provides comprehensive protection for industrial, commercial and infrastructure power networks.

This breaker uses a withdrawable construction for integration with a compatible Emax 2 fixed part, helping simplify inspection, servicing and replacement within switchboard installations. Its Ekip Touch LSIG solid-state electronic release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, delivering comprehensive protection for the electrical distribution system.

With an ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s, the E2.2B 1600 is suitable for demanding main distribution, incomer and feeder applications. The moving part is supplied with four auxiliary contacts and circuit-breaker open/closed position indication, providing a robust solution for modern low-voltage switchboards.

Advanced LSIG Protection for Low-Voltage Power Distribution

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 earth-fault conditions before they can damage cables, busbars, switchgear or connected equipment. The E2.2B 1600 combines a substantial 1600 A current rating with 42 kA short-circuit performance, making it well suited to main distribution and high-current feeder applications.

The Ekip Touch LSIG electronic trip unit provides long-time overload, short-time selective, instantaneous short-circuit and ground-fault protection. The additional ground-fault function distinguishes this LSIG version from LSI variants, providing enhanced protection against earth faults while supporting coordinated protection across complex low-voltage distribution networks.

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.
