Why Choose the ABB E4.2V 4000 Ekip Touch LI 4p WMP Air Circuit Breaker?
The ABB E4.2V 4000 Ekip Touch LI 4p WMP, order code 1SDA073204R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding high-current low-voltage power distribution systems. Rated at 4000 A, this withdrawable moving part combines the E4.2 frame with ABB's V short-circuit performance level and an advanced Ekip Touch LI electronic trip unit.
The Ekip Touch LI release provides long-time overload (L) and instantaneous short-circuit (I) protection. Its overload protection is adjustable from 1600–4000 A, while the instantaneous short-circuit release is adjustable from 6000–60000 A. The touchscreen interface provides convenient access to protection settings and operating information while retaining a focused LI protection architecture.
The E4.2V 4000 has a rated operational voltage of 690 V AC and provides an ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC and 100 kA at 500–690 V AC. Its 100 kA short-time withstand current for 1 s, four-pole construction and withdrawable moving-part design make it well suited to high-capacity switchboards where very high prospective fault currents and efficient maintainability are key considerations.

High-Performance LI Protection for High-Current Distribution
Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage electrical networks. The E4.2V platform combines a substantial 4000 A continuous-current rating with up to 150 kA short-circuit breaking capability, making it particularly suitable for installations where very high prospective fault currents must be safely interrupted.
The Ekip Touch LI trip unit provides adjustable long-time overload and instantaneous short-circuit protection through a touchscreen interface. This focused protection arrangement is suited to applications where delayed short-circuit and integrated earth-fault functions are not required, while the E4.2V platform provides the high breaking and withstand performance needed for demanding main distribution and feeder applications.
Typical Applications
- Main low-voltage distribution switchboards.
- High-fault-level industrial electrical networks.
- Transformer secondary 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.
