1SDA071863R1 ABB E6.2H 4000 Ekip Dip LSIG 4p FHR Air Circuit Breaker

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

The ABB 1SDA071863R1 is a high-performance Emax 2 air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage power-distribution systems. Identified as the E6.2H 4000 Ekip Dip LSIG 4p FHR, this four-pole fixed circuit breaker combines a 4000 A rated current with ABB’s Ekip Dip LSIG solid-state electronic trip unit.

As part of the ABB SACE Emax 2 series, the E6.2H provides substantial short-circuit performance for critical industrial and infrastructure installations. The Ekip Dip LSIG release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, delivering comprehensive electronic protection for high-current electrical networks.

With a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a short-time withstand current of 100 kA for 1 s, the 1SDA071863R1 is engineered for installations with high prospective fault currents. Its four-pole fixed construction and rear horizontal terminals provide a robust configuration for permanent integration into high-current low-voltage switchboards and distribution assemblies.

Comprehensive High-Capacity Power Distribution Protection

Air circuit breakers such as the ABB Emax 2 E6.2H provide switching, isolation and protection for high-current low-voltage electrical systems. The E6.2H 4000 combines a substantial 4000 A current rating with 100 kA short-circuit breaking capability at 440 V AC and a 100 kA one-second withstand rating, making it particularly suitable for critical distribution points with high prospective fault currents.

The Ekip Dip LSIG electronic trip unit provides long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. These protection functions allow the breaker to safeguard transformers, busbars, cables and connected equipment against a broad range of electrical faults while supporting selective coordination and continuity of service.
