1SDA071278R1 ABB E6.2V 5000 Ekip Hi-Touch LSI 3p FHR Air Circuit Breaker

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

The ABB E6.2V 5000 Ekip Hi-Touch LSI 3p FHR, order code 1SDA071278R1, 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 LSI electronic trip unit.

The Ekip Hi-Touch LSI release provides adjustable long-time, short-time and instantaneous protection, helping safeguard electrical networks against overload and short-circuit conditions. Its touch-sensitive display provides access to protection settings and system information, while integrated Ekip Measuring Pro and Network Analyzer functionality extends monitoring and power-quality analysis capabilities.

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 demanding installations with very high prospective fault currents. This configuration features a fixed, three-pole design with rear horizontal terminals, making it suitable for main incomers and high-capacity feeders in industrial and critical power switchboards.
