Why Choose the ABB E4.2S 4000 Ekip Hi-Touch LSIG 4p WMP Air Circuit Breaker?
The ABB E4.2S 4000 Ekip Hi-Touch LSIG 4p WMP, order code 1SDA073189R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, switching and advanced monitoring in demanding low-voltage power distribution systems. Rated at 4000 A, this withdrawable moving part combines the E4.2 frame with ABB's S short-circuit performance level and an advanced Ekip Hi-Touch LSIG electronic trip unit.
The Ekip Hi-Touch LSIG release provides long-time overload (L), short-time selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. The Hi-Touch platform combines comprehensive electronic protection with advanced measurement and monitoring functionality, providing a sophisticated solution for critical industrial, commercial and infrastructure power distribution networks.
The E4.2S 4000 has a rated operational voltage of 690 V AC and provides an ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC and 66 kA at 500–690 V AC. Its 66 kA short-time withstand current for both 1 s and 3 s, four-pole construction and withdrawable design make it particularly suitable for high-current systems requiring strong selectivity and maintainability.

Advanced LSIG Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage electrical networks. The E4.2S platform combines a substantial 4000 A continuous-current rating with strong short-circuit breaking and withstand capabilities, making it suitable for main switchboards and other high-capacity distribution systems where selectivity and continuity of supply are important.
The Ekip Hi-Touch LSIG trip unit provides a comprehensive protection architecture covering overloads, delayed and instantaneous short circuits, and earth faults. Combined with the E4.2S breaker's 66 kA short-time withstand capability for up to 3 s, this allows appropriately engineered systems to achieve selective coordination between upstream and downstream protective devices while providing advanced monitoring of critical electrical distribution assets.
Typical Applications
- Main low-voltage distribution switchboards.
- High-current industrial power distribution systems.
- Transformer and generator protection.
- Main and high-current feeder protection.
- Manufacturing plants and process facilities.
- Data centres and critical power infrastructure.
- Large commercial and infrastructure installations.
- High-capacity switchgear and power distribution systems.
