Why Choose the ABB E4.2H 3200 Ekip G Hi-Touch LSIG 4p F HR Air Circuit Breaker?
The ABB E4.2H 3200 Ekip G Hi-Touch LSIG 4p F HR, order code 1SDA071800R1, is a high-performance four-pole air circuit breaker (ACB) designed for generator protection and demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 series, it combines a 3200 A rated current with the advanced Ekip G Hi-Touch LSIG electronic protection release and the high short-circuit performance of the E4.2H frame.
The Ekip G Hi-Touch LSIG trip unit combines long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection with advanced functions developed for generator applications. Its sophisticated measurement, monitoring and protection capabilities make this breaker particularly suitable for generator switchboards, critical power systems and installations where detailed electrical supervision is required.
The E4.2H 3200 provides an ultimate short-circuit breaking capacity of 100 kA at 415 V AC and 85 kA at 690 V AC. This four-pole version is supplied as a fixed circuit breaker with rear flat horizontal terminals, providing a robust solution for high-current generator and distribution switchboards.

Advanced Generator and LSIG Power Protection
Generator circuits present protection requirements that differ from conventional utility-fed distribution networks. The ABB Ekip G Hi-Touch platform is designed to provide advanced generator-oriented protection while retaining comprehensive LSIG protection against overloads, short circuits and earth faults. This helps safeguard generators, cables, busbars, switchgear and connected equipment while supporting coordinated operation across critical power systems.
The E4.2H frame adds substantial fault-interruption performance, providing 100 kA Icu at 415 V AC, 85 kA Icu at 690 V AC and 85 kA Icw for 1 s. Combined with the Ekip G Hi-Touch release, the 1SDA071800R1 is particularly suited to generator switchboards and high-power distribution systems where advanced protection, monitoring and dependable short-circuit interruption are essential.
Typical Applications
- Generator protection and generator switchboards.
- Standby and emergency power generation systems.
- Critical power distribution networks.
- Main low-voltage electrical distribution switchboards.
- Industrial power generation and distribution systems.
- Manufacturing and process facilities.
- Large commercial buildings and infrastructure installations.
- High-current feeder and distribution circuits.
- Systems requiring integrated earth-fault and generator-specific protection.
