Why Choose the ABB E4.2V 2500 Ekip Hi-Touch LSIG 4p F HR Air Circuit Breaker?
The ABB E4.2V 2500 Ekip Hi-Touch LSIG 4p F HR, order code 1SDA071759R1, is a high-performance four-pole air circuit breaker (ACB) designed for advanced protection and switching in demanding low-voltage power distribution systems. As part of the ABB SACE Emax 2 series, it combines a 2500 A rated uninterrupted current with the advanced Ekip Hi-Touch LSIG electronic trip unit and the exceptional short-circuit performance of the E4.2V frame.
This fixed circuit breaker incorporates the Ekip Hi-Touch LSIG electronic protection release, providing long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. The Hi-Touch platform extends the Emax 2 protection and measurement capabilities for sophisticated electrical installations where accurate protection settings, system monitoring and selective coordination are important requirements.
With an ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a 100 kA short-time withstand current for 1 s, the E4.2V 2500 is engineered for systems with exceptionally high prospective fault currents. This version features a fixed four-pole construction with rear horizontal connections, making it suitable for integration into high-capacity industrial, commercial and infrastructure switchboards.
