Why Choose the ABB E4.2S 3200 Ekip G Touch LSIG 4p WMP Air Circuit Breaker?
The ABB E4.2S 3200 Ekip G Touch LSIG 4p WMP, order code 1SDA073137R1, is a high-current four-pole air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 3200 A, it is engineered for demanding low-voltage power distribution and generator applications requiring advanced electronic protection, high short-circuit performance and service-friendly withdrawable construction.
This E4.2S breaker is equipped with an Ekip G Touch LSIG solid-state electronic trip unit. The generator-oriented Ekip G Touch platform combines long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection with an advanced touchscreen interface, providing comprehensive protection for generators and associated distribution systems.
The S performance level provides a rated ultimate short-circuit breaking capacity of 85 kA at 440 V AC, while the E4.2 frame provides a rated short-time withstand current of 66 kA for 1 s. The WMP configuration is the moving part of a withdrawable Emax 2 breaker system, enabling efficient inspection, maintenance and replacement when installed with the corresponding fixed part.

Advanced Generator and Power-Distribution Protection
The ABB E4.2S 3200 combines the high-current switching capability of the SACE Emax 2 platform with the generator-oriented functionality of the Ekip G Touch electronic release. Its LSIG protection functions provide coordinated response to sustained overloads, delayed short circuits, severe instantaneous faults and earth faults, helping protect generators and connected low-voltage distribution equipment.
With an 85 kA breaking capacity at 440 V AC, 66 kA short-time withstand capability for 1 s and a 3200 A current rating, the E4.2S is suited to high-power installations where robust fault handling and maintainability are important. Its withdrawable architecture allows the moving breaker section to be removed from the compatible fixed part for inspection or servicing.
Typical Applications
- Generator protection and generator switchboards.
- Main incoming protection for high-current low-voltage switchboards.
- Industrial power generation and distribution systems.
- Generator-to-bus and critical-power distribution systems.
- Manufacturing and process plants.
- Data centres and critical infrastructure.
- Utility and infrastructure power systems.
- High-current feeder and distribution protection.
