Why Choose the ABB E1.2C 800 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker?
The ABB E1.2C 800 Ekip G Hi-Touch LSIG 4p WMP, order code 1SDA072740R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for advanced protection, switching and power management in low-voltage distribution and generator applications. As part of the ABB SACE Emax 2 E1.2 series, it combines an 800 A rated current with the advanced Ekip G Hi-Touch LSIG electronic trip unit.
The Ekip G Hi-Touch LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection together with advanced generator protection, measurement and monitoring capabilities. Its high-level electronic interface supports detailed supervision and flexible protection configuration, making this breaker particularly suitable for generator installations, critical power systems and sophisticated industrial distribution networks.
The E1.2C performance level provides an ultimate short-circuit breaking capacity of 50 kA at 400 V AC. Its withdrawable construction enables the moving breaker to be separated from the corresponding fixed chassis for maintenance or inspection, while the four-pole arrangement provides switching and protection across all four conductors in suitable low-voltage systems.
