1SDA072383R1 ABB E2.2N 2000 Ekip Dip LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2N 2000 Ekip Dip LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2N 2000 Ekip Dip LSIG 3p WMP, order code 1SDA072383R1, 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 E2.2N frame with a 2000 A rated uninterrupted current and ABB's Ekip Dip 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, supporting efficient inspection, servicing and replacement within switchboard installations. Its Ekip Dip LSIG solid-state electronic release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection, with protection settings configured through DIP switches.

With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 66 kA at 400/415 V AC, the E2.2N 2000 provides substantial fault-current interruption capability. Its 2000 A current rating, three-pole configuration, withdrawable moving-part construction and four auxiliary contacts make it suitable for main distribution, incomer and high-current feeder protection.

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 ground-fault conditions before they can damage cables, busbars, switchgear or connected equipment. The E2.2N 2000 combines a substantial 2000 A current rating with 66 kA short-circuit breaking capacity, making it well suited to main distribution and high-current feeder applications.

The Ekip Dip LSIG electronic trip unit provides long-time overload, short-time selective, instantaneous short-circuit and ground-fault protection. Adjustable protection settings allow the breaker response to be coordinated with other protective devices throughout the electrical network, helping improve selectivity, continuity of service and protection of valuable distribution equipment.

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.
