1SDA071247R1 ABB E6.2V 4000 Ekip G Touch LSIG 3p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 4000 Ekip G Touch LSIG 3p FHR Air Circuit Breaker?

The ABB E6.2V 4000 Ekip G Touch LSIG 3p FHR, order code 1SDA071247R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for protection and control of high-current low-voltage distribution and generator systems. As part of the advanced ABB Emax 2 E6.2 series, this fixed three-pole breaker combines a 4000 A rated current with the sophisticated Ekip G Touch LSIG electronic trip unit.

The Ekip G Touch LSIG protection release provides long-time, short-time, instantaneous and earth-fault protection together with functions developed for generator protection applications. Its touchscreen interface supports intuitive configuration, measurement and monitoring, helping operators manage demanding electrical installations and coordinate protection throughout the distribution system.

With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 150 kA at 400/415 V AC, the E6.2V is engineered for installations with exceptionally high prospective fault currents. This configuration features a fixed, three-pole design with rear horizontal terminals and four auxiliary change-over contacts for breaker status signalling.
