Why Choose the ABB E2.2S 800 Ekip Dip LI 3p WMP Air Circuit Breaker?
The ABB E2.2S 800 Ekip Dip LI 3p WMP, order code 1SDA072251R1, 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 an 800 A rated current 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 essential electronic circuit protection while providing adjustable protection settings suited to industrial and commercial distribution networks.
This E2.2S version is a withdrawable moving part (WMP) for use with the corresponding Emax 2 fixed part. The E2.2S performance level provides a rated ultimate short-circuit breaking capacity of 85 kA at 440 V AC and a short-time withstand current of 66 kA for 1 s, making it suitable for demanding high-fault-level installations.
Key Advantages
- High-performance ABB SACE Emax 2 air circuit breaker for low-voltage distribution.

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 for severe short circuits, helping isolate electrical faults before they can cause more extensive damage to cables, switchgear and connected equipment.
The E2.2S frame is engineered for installations requiring high breaking and short-time withstand performance. Its withdrawable construction allows the breaker moving part to be separated from the fixed switchboard section for inspection, maintenance or replacement, while auxiliary contacts and breaker position indication facilitate integration into electrical control and monitoring systems.
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 protection and distribution.
- Infrastructure and utility electrical installations.
- High-fault-level three-phase distribution networks.
- Withdrawable switchgear requiring electronic LI protection.
