The ABB E4.2H 4000 Ekip Touch LSI 3p F HR, order code 1SDA071215R1, is a high-performance Emax 2 air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, it combines a 4000 A rated uninterrupted current with high short-circuit performance for industrial, infrastructure and critical power applications.
This fixed three-pole circuit breaker incorporates the Ekip Touch LSI solid-state electronic trip unit, providing adjustable long-time overload, selective short-time and instantaneous short-circuit protection. The Ekip Touch platform provides an intuitive touchscreen interface for configuring protection parameters and accessing breaker information, supporting effective selectivity and coordination within sophisticated electrical distribution systems.
With a rated uninterrupted current of 4000 A and a rated operational voltage of 690 V AC, the E4.2H provides an ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC. Its fixed three-pole construction, rear flat horizontal terminals and high short-time withstand capability make it suitable for integration into high-current low-voltage switchboards.
Air circuit breakers such as the ABB Emax 2 E4.2H protect high-current low-voltage distribution systems against overload and short-circuit conditions while providing controlled switching and isolation. With a 4000 A current rating, 100 kA breaking capacity at 400–440 V AC and substantial short-time withstand capability, this E4.2H configuration is suitable for main distribution points and other critical high-current sections of electrical installations.
The Ekip Touch LSI electronic trip unit combines adjustable long-time overload protection with selective short-time and instantaneous short-circuit protection. Its touchscreen interface simplifies configuration, while adjustable protection thresholds allow the breaker to be coordinated with upstream and downstream protective devices to improve selectivity and continuity of supply.
