1SDA072346R1 ABB E2.2N 1600 Ekip Touch LSIG 3p WMP Air Circuit Breaker

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

The ABB E2.2N 1600 Ekip Touch LSIG 3p WMP, order code 1SDA072346R1, is a SACE Emax 2 air circuit breaker moving part designed for protection and switching in demanding low-voltage AC power distribution systems. This three-pole E2.2N model combines a rated uninterrupted current of 1600 A with ABB's Ekip Touch LSIG solid-state electronic protection release.

The Ekip Touch LSIG trip unit provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. Its touchscreen interface supports intuitive protection configuration and access to electrical and operating information, while the LSIG protection architecture provides comprehensive fault protection for complex distribution networks.

This E2.2N version is supplied as a withdrawable moving part (WMP) for use with the corresponding Emax 2 fixed part. It is rated for 1600 A, provides an ultimate short-circuit breaking capacity of 66 kA at 400 V AC, 50 Hz, and incorporates four auxiliary change-over contacts plus circuit-breaker open/closed indication for switchboard integration.

Key Advantages

• ABB SACE Emax 2 E2.2N air circuit breaker platform for demanding low-voltage power distribution.
• 1600 A rated uninterrupted current for high-current industrial and commercial circuits.

Comprehensive LSIG Protection for High-Current Power Distribution

The ABB SACE Emax 2 E2.2N is designed to protect high-current low-voltage distribution circuits against overload, short-circuit and earth-fault conditions. Its Ekip Touch LSIG release combines long-time overload protection with short-time delayed, instantaneous and earth-fault functions, enabling comprehensive protection and supporting coordinated fault isolation throughout the electrical network.

The withdrawable design allows the breaker moving part to be separated from its compatible fixed chassis for inspection, servicing or replacement. Combined with electronic protection, four auxiliary change-over contacts, breaker-position indication and optional motor operation, the E2.2N is well suited to modern switchboards where maintainability, operational continuity and dependable high-current protection are important.

Typical Applications

• Industrial low-voltage power distribution switchboards.
• Main incomer and high-current feeder protection.
• Manufacturing and process-industry electrical systems.
• Commercial building power distribution.
• Transformer secondary distribution systems.
• Data centres and critical power infrastructure.
• Utility and infrastructure electrical installations.
• Three-phase AC networks requiring comprehensive LSIG protection.
• High-fault-current distribution systems requiring 66 kA breaking capacity.
• Withdrawable switchgear requiring maintainable high-current circuit protection.
