1SDA071903R1 ABB E6.2V 5000 Ekip Dip LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 5000 Ekip Dip LSIG 4p FHR Air Circuit Breaker?

The ABB 1SDA071903R1 is a high-capacity Emax 2 air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage power-distribution systems. Identified as the E6.2V 5000 Ekip Dip LSIG 4p FHR, this four-pole fixed circuit breaker combines a substantial 5000 A rated current with ABB’s Ekip Dip LSIG electronic trip unit.

As part of the ABB SACE Emax 2 E6.2V series, the breaker provides exceptionally high short-circuit performance for critical industrial and infrastructure installations. The Ekip Dip LSIG release provides adjustable long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, with protection settings configured through DIP switches.

With a rated operational voltage of 690 V AC, the E6.2V platform provides an ultimate short-circuit breaking capacity of 150 kA at 380–440 V AC, 130 kA at 500–525 V AC and 100 kA at 690 V AC. Its four-pole fixed construction and rear horizontal terminals provide a robust configuration for permanent integration into high-capacity low-voltage switchboards.

Comprehensive High-Capacity Circuit Protection

The ABB Emax 2 E6.2V platform is designed for high-current low-voltage systems where exceptional short-circuit performance and selective protection are required. With a 5000 A current rating and breaking capacity reaching 150 kA, the E6.2V 5000 is particularly suited to critical distribution positions exposed to very high prospective fault currents.

The Ekip Dip LSIG electronic trip unit provides adjustable long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. These functions help protect transformers, busbars, cables and connected equipment against a broad range of electrical faults while allowing protection characteristics to be coordinated with other devices for improved selectivity and continuity of service.

Typical Applications

• Main incomer protection in high-current low-voltage switchboards.
• Industrial power distribution systems.
• Transformer and installation protection.
• Manufacturing and process plants.
• Data centres and critical power installations.
• Utility and infrastructure electrical distribution.
• Large electrical distribution panels and switchboards.
• High-current installations requiring integrated earth-fault protection.
