1SDA071279R1 ABB E6.2V 5000 Ekip Hi-Touch LSIG 3p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 5000 Ekip Hi-Touch LSIG 3p FHR Air Circuit Breaker?

The ABB E6.2V 5000 Ekip Hi-Touch LSIG 3p FHR, order code 1SDA071279R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for advanced protection, measurement and control of high-current low-voltage electrical distribution systems. As part of the ABB Emax 2 E6.2 series, this fixed three-pole breaker combines a 5000 A rated current with the advanced Ekip Hi-Touch LSIG electronic trip unit.

The Ekip Hi-Touch LSIG protection release provides long-time, short-time, instantaneous and earth-fault protection for comprehensive electrical system protection. Its touchscreen interface provides intuitive access to protection settings and system information, while advanced measurement and power-quality analysis capabilities support detailed monitoring of demanding electrical networks.

With a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 150 kA at 400/415 V AC and a short-time withstand current of 100 kA, the E6.2V is engineered for installations with exceptionally high prospective fault currents. This configuration features a fixed, three-pole design with rear flat horizontal terminals for integration into high-capacity low-voltage switchboards.
