Why Choose the ABB E2.2S 800 Ekip Dip LSI 3p WMP Air Circuit Breaker?
The ABB E2.2S 800 Ekip Dip LSI 3p WMP, order code 1SDA072252R1, 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 LSI electronic protection release.
The integrated Ekip Dip LSI trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. This combination enables selective and configurable protection of electrical distribution circuits while helping coordinate the breaker with upstream and downstream protective devices.
This E2.2S version is a withdrawable moving part (WMP) for use with the corresponding Emax 2 fixed part. With a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 85 kA at 400 V AC and robust withdrawable construction, it is suited to demanding industrial, commercial and infrastructure power-distribution installations.

Reliable and Selective Protection for 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 LSI release combines long-time overload protection with short-time delayed and instantaneous short-circuit functions, allowing protection settings to be coordinated with other devices in the distribution network.
The E2.2S frame is designed for installations requiring high breaking and short-time withstand performance. Its withdrawable construction enables the moving part to be separated from the compatible fixed switchboard section for maintenance or replacement, while auxiliary contacts and breaker status indication support integration with 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 distribution systems.
- Infrastructure and utility electrical installations.
- High-fault-level three-phase distribution networks.
- Withdrawable switchgear requiring selective LSI protection.
