1SDA071876R1 ABB E6.2V 4000 Ekip Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 4000 Ekip Touch LSIG 4p FHR Air Circuit Breaker?

The ABB 1SDA071876R1 is a high-performance Emax 2 air circuit breaker (ACB) designed for protection, switching and control in demanding low-voltage power-distribution systems. Identified as the E6.2V 4000 Ekip Touch LSIG 4p FHR, this four-pole fixed circuit breaker combines a 4000 A rated current with ABB’s advanced Ekip Touch LSIG electronic trip unit.

As part of the ABB SACE Emax 2 E6.2V series, this breaker provides exceptionally high short-circuit performance for critical industrial and infrastructure installations. The Ekip Touch LSIG release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, while its touchscreen interface supports intuitive configuration and access to operating information.

With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 150 kA at 415 V AC, the 1SDA071876R1 is engineered for high-current installations with substantial prospective fault levels. Its four-pole fixed construction and rear horizontal terminals provide a robust configuration for permanent integration into high-capacity low-voltage switchboards and distribution assemblies.

Advanced High-Capacity Circuit Protection and Power Management

Air circuit breakers such as the ABB Emax 2 E6.2V provide switching, isolation and protection for high-current low-voltage electrical systems. The E6.2V 4000 combines a substantial 4000 A current rating with 150 kA short-circuit breaking capability at 415 V AC, making it particularly suitable for critical distribution points where extremely high prospective fault currents may occur.

The Ekip Touch LSIG electronic trip unit provides configurable long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. Combined with the advanced monitoring, communication and power-management capabilities available within the Emax 2 platform, this helps protect transformers, busbars, cables and connected equipment while supporting selectivity, continuity of service and modern electrical automation strategies.
