Why Choose the ABB E2.2B 2000 Ekip Dip LSIG 3p WMP Air Circuit Breaker?
The ABB E2.2B 2000 Ekip Dip LSIG 3p WMP, order code 1SDA072373R1, is a SACE Emax 2 air circuit breaker moving part designed for protection and switching in high-current low-voltage AC distribution systems. This three-pole E2.2B model has a rated current of 2000 A and is equipped with ABB's Ekip Dip LSIG solid-state electronic protection release.
The Ekip Dip LSIG release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. Protection thresholds are configured using DIP switches, providing a straightforward method of setting the breaker for coordinated distribution protection without requiring a touchscreen interface.
This model is supplied as a withdrawable moving part (WMP) for use with the corresponding Emax 2 fixed part. The E2.2B performance level provides an ultimate short-circuit breaking capacity of 42 kA from 380 V through 690 V AC, while four auxiliary change-over contacts, trip signalling and open/closed indication support integration into industrial switchboards.

Comprehensive LSIG Protection for High-Current Power Distribution
The ABB SACE Emax 2 E2.2B provides comprehensive electronic protection for high-current low-voltage distribution systems. Its Ekip Dip LSIG release combines long-time overload, short-time delayed, instantaneous short-circuit and earth-fault protection, with independently adjustable thresholds helping engineers coordinate protection and isolate electrical faults selectively within the distribution network.
The withdrawable construction improves maintainability by allowing the breaker moving part to be separated from its compatible fixed part for inspection, servicing or replacement. Together with four auxiliary change-over contacts, trip signalling and open/closed indication, this makes the E2.2B suitable for switchboards where dependable protection, clear operating status and efficient maintenance 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.
- Distribution systems requiring adjustable earth-fault protection.
- Withdrawable switchgear requiring maintainable 2000 A circuit protection.
