1SDA072519R1 ABB E4.2H 3200 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E4.2H 3200 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E4.2H 3200 Ekip Hi-Touch LSIG 3p WMP, order code 1SDA072519R1, is a high-performance three-pole air circuit breaker (ACB) moving part from the ABB SACE Emax 2 range, engineered for demanding low-voltage power distribution systems. Combining the E4.2H frame with a 3200 A rated uninterrupted current and ABB's advanced Ekip Hi-Touch LSIG electronic trip unit, it provides comprehensive overload, short-circuit and ground-fault protection for high-current industrial, commercial and critical infrastructure networks.

This breaker uses a withdrawable construction for integration with a compatible Emax 2 fixed part, supporting efficient inspection, servicing and replacement within switchboard installations. Its Ekip Hi-Touch LSIG solid-state electronic release combines long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection with the advanced measurement, monitoring and supervision capabilities of the Hi-Touch platform.

The E4.2H 3200 delivers an ultimate short-circuit breaking capacity of 100 kA at 400/415 V AC and 85 kA at 690 V AC, together with a rated short-time withstand current of 85 kA for 1 s. Its combination of a 3200 A current rating, comprehensive LSIG protection, high fault-current capability and withdrawable construction makes the 1SDA072519R1 particularly suitable for main distribution, incomer and high-current feeder applications.
