Why Choose the ABB 1SDA129011R1 E4.3V 2000 Ekip Aware LSIG Air Circuit Breaker?
The ABB 1SDA129011R1, product designation E4.3V 2000 Ekip Aware LSIG 4p WMP, is a high-performance four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 3 range. Rated at 2000 A, it combines the E4.3 frame and V performance level with ABB's advanced Ekip Aware LSIG electronic trip unit for comprehensive low-voltage power-distribution protection.
The Ekip Aware LSIG release provides long-time (L), short-time (S), instantaneous (I) and ground-fault (G) protection. This comprehensive protection package enables the breaker to respond to overloads, selective short-circuit conditions, severe instantaneous faults and earth-fault currents, supporting coordinated protection of demanding industrial and infrastructure distribution networks.
The E4.3V platform provides a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 s. As a withdrawable moving part (WMP), the 1SDA129011R1 is designed for use with the corresponding Emax 3 fixed part, facilitating isolation, inspection, maintenance and replacement within serviceable switchboard architectures.

Comprehensive Protection with Ekip Aware LSIG
The Ekip Aware LSIG electronic trip unit combines four essential protection functions within one coordinated platform. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during high-current faults, instantaneous protection provides rapid interruption of severe short circuits, and ground-fault protection detects current flowing through unintended earth paths.
Combined with the E4.3V breaker's high short-circuit performance, these functions make the 1SDA129011R1 suitable for installations where both high fault-current capability and sophisticated protection coordination are required. Its withdrawable architecture further supports maintenance and operational continuity by allowing the breaker moving part to be isolated and removed from its compatible fixed part.
Typical Applications
- Main incoming low-voltage switchboards.
- High-current industrial distribution systems.
- Transformer secondary protection.
- Generator and utility incomer applications.
- Bus-section and distribution feeder protection.
- Manufacturing and process-industry facilities.
- Data centres and critical-power infrastructure.
- Applications requiring LSIG protection and high short-circuit performance.
