1SDA072281R1 ABB E2.2S 1000 Ekip Dip LI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2S 1000 Ekip Dip LI 3p WMP Air Circuit Breaker?

The ABB E2.2S 1000 Ekip Dip LI 3p WMP, order code 1SDA072281R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and switching in low-voltage AC power distribution systems. As part of the ABB Emax 2 E2.2 series, this three-pole breaker combines a rated current of 1000 A with the Ekip Dip LI solid-state electronic protection release.

The integrated Ekip Dip LI trip unit provides long-time overload and instantaneous short-circuit protection. This combination delivers dependable electronic protection against sustained overcurrents and severe short circuits while providing adjustable protection settings for coordination within industrial and commercial electrical distribution networks.

This E2.2S version is a withdrawable moving part (WMP) for use with the corresponding Emax 2 fixed part. It has a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC and a rated short-time withstand current of 66 kA for 1 s, making it suitable for demanding high-current and high-fault-level installations.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current electrical distribution circuits against overload and short-circuit conditions. The Ekip Dip LI electronic release combines long-time protection against sustained overcurrent with instantaneous operation during severe short circuits, helping isolate electrical faults before they can cause extensive damage to cables, switchgear and connected equipment.

The E2.2S frame combines high breaking capacity with strong short-time withstand performance, supporting coordinated protection in demanding low-voltage networks. Its withdrawable construction allows the moving part to be separated from the compatible fixed part for inspection, servicing or replacement, making it particularly suitable for switchboards where maintainability and continuity of operation are important.

Typical Applications

• Industrial low-voltage power distribution switchboards.
• Main incomer and feeder circuit protection.
• Manufacturing and process-industry electrical systems.
• Commercial building power distribution.
• Transformer secondary distribution systems.
• Infrastructure and utility electrical installations.
• High-fault-level three-phase AC distribution networks.
• Withdrawable switchgear requiring electronic LI protection.
