1SDA071931R1 ABB E6.2V 6300 Ekip Dip LI 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 6300 Ekip Dip LI 4p FHR Air Circuit Breaker?

The ABB E6.2V 6300 Ekip Dip LI 4p FHR, order code 1SDA071931R1, is a high-performance four-pole SACE Emax 2 air circuit breaker designed for protection and switching in very high-current low-voltage power-distribution systems. Part of the ABB SACE Emax 2 E6.2 series, this fixed breaker combines a 6300 A rated uninterrupted current with the dependable Ekip Dip LI electronic trip unit.

The E6.2V performance level provides exceptional fault-interruption capability, with a rated ultimate short-circuit breaking capacity of 150 kA at the principal low-voltage system levels and 100 kA at 690 V AC. Its Ekip Dip LI release provides long-time overload and instantaneous short-circuit protection, offering straightforward electronic protection for installations where advanced LSIG functions are not required.

This version is a four-pole fixed air circuit breaker with rear flat horizontal (FHR) terminals and a rated voltage of 690 V. Combining the maximum 6300 A E6.2 current rating with V-level short-circuit performance, the 1SDA071931R1 is particularly suited to main switchboards, large industrial installations, transformer secondaries and critical infrastructure requiring dependable high-current circuit protection.

Reliable LI Protection for Very High-Current Distribution

Very high-capacity electrical distribution systems require circuit breakers capable of carrying substantial continuous current while safely interrupting severe short-circuit conditions. The ABB E6.2V combines a 6300 A rated uninterrupted current with up to 150 kA ultimate short-circuit breaking capacity, providing a robust protection platform for main incomers, transformer secondaries, busbar systems and high-current feeders.

The Ekip Dip LI trip unit provides electronic long-time overload and instantaneous short-circuit protection with straightforward DIP-switch adjustment. This makes the 1SDA071931R1 particularly suitable where dependable electronic protection, very high current-carrying capability and exceptional fault interruption are required without the additional protection and measurement functions of more advanced Ekip Touch releases.

Typical Applications

• Main incoming protection in very high-current low-voltage switchboards.
• Industrial power-distribution systems.
• Large manufacturing and process facilities.
• Transformer secondary protection.
• High-current feeder and busbar protection.
• Data centres and critical power infrastructure.
• Large commercial and infrastructure electrical installations.
• Networks requiring straightforward LI protection with very high short-circuit performance.
