Why Choose the ABB E4.2V 3200 Ekip G Touch LSIG 3p F HR Air Circuit Breaker?
The ABB E4.2V 3200 Ekip G Touch LSIG 3p F HR, order code 1SDA071177R1, is a high-performance Emax 2 air circuit breaker (ACB) designed for generator protection and demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, it combines a 3200 A rated uninterrupted current with exceptionally high short-circuit performance for generating plants, industrial installations and critical power infrastructure.
This fixed three-pole circuit breaker incorporates the Ekip G Touch LSIG solid-state electronic trip unit, combining long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection with functions developed for generator applications. The Ekip G Touch platform provides a touchscreen interface for protection configuration, measurement and monitoring, supporting sophisticated generator and power-management systems.
With a rated uninterrupted current of 3200 A and an ultimate short-circuit breaking capacity of 150 kA at 440 V AC, the E4.2V is engineered for installations with exceptionally high prospective fault currents. Its rated short-time withstand current of 100 kA for 1 s, fixed three-pole construction and rear horizontal terminals make it particularly suitable for high-current generator switchboards and critical low-voltage distribution assemblies.
