Why Choose the ABB E4.2V 3200 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker?
The ABB E4.2V 3200 Ekip Hi-Touch LSIG 4p FHR, order code 1SDA071809R1, is a high-performance four-pole Emax 2 air circuit breaker designed for protection, switching, measurement and power management in demanding low-voltage electrical distribution systems. Part of the advanced ABB SACE Emax 2 E4.2 series, it combines a 3200 A rated uninterrupted current with the sophisticated Ekip Hi-Touch LSIG solid-state electronic trip unit.
The E4.2V performance level provides exceptional fault-interruption capability, including a rated ultimate short-circuit breaking capacity of 150 kA at 400/415 V AC. The Ekip Hi-Touch LSIG trip unit provides long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection, making this breaker suitable for critical distribution systems where precise protection coordination and comprehensive fault coverage are required.
This version is a four-pole fixed circuit breaker equipped with rear horizontal (FHR) terminals. With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and short-time withstand current of 100 kA for 1 s, the 1SDA071809R1 provides robust protection for high-current industrial switchboards, infrastructure and critical power-distribution installations.

Advanced Protection and Power Management for Critical Distribution
Air circuit breakers such as the ABB E4.2V protect high-current low-voltage networks against overloads, short circuits and earth faults while providing the switching performance required for major distribution circuits. The combination of a 3200 A current rating, 150 kA breaking capacity at 400/415 V AC and configurable LSIG protection makes the 1SDA071809R1 particularly suitable for installations where fault discrimination, selective coordination and continuity of service are essential.
The Ekip Hi-Touch LSIG platform combines sophisticated electronic protection with the advanced measurement and monitoring capabilities of the Emax 2 system. Integrated earth-fault protection adds an important layer of protection for cables, busbars, transformers and other critical equipment, while the breaker can be incorporated into modern power-management and automation architectures.
Typical Applications
- Main incoming protection in low-voltage switchboards.
- Industrial power-distribution systems.
- Large manufacturing and process facilities.
- Data centres and critical power infrastructure.
- Commercial and infrastructure electrical installations.
- Transformer and distribution feeder protection.
- High-current electrical distribution assemblies.
- Networks requiring high breaking capacity and integrated earth-fault protection.
