1SDA071991R1 ABB E6.2V/f 5000 Ekip Dip LI 4p F HR Air Circuit Breaker

Why Choose the ABB E6.2V/f 5000 Ekip Dip LI 4p F HR Air Circuit Breaker?

The ABB E6.2V/f 5000 Ekip Dip LI 4p F HR, order code 1SDA071991R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 series, designed for protection and switching in demanding low-voltage power distribution systems. With a rated uninterrupted current of 5000 A and a very high short-circuit breaking capacity, it is suited to major industrial, commercial and infrastructure electrical installations.

This circuit breaker incorporates the Ekip Dip LI solid-state electronic trip unit, providing long-time overload and instantaneous short-circuit protection. The Ekip Dip platform provides straightforward electronic protection adjustment for applications where dependable circuit protection is required without the additional short-time or earth-fault functions found on LSI and LSIG releases.

The 1SDA071991R1 features a four-pole configuration with a full-size neutral, fixed installation and rear horizontal terminals. Its E6.2V/f performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, while its rated short-time withstand current is 100 kA for 1 s, making it suitable for high-current distribution systems with substantial prospective fault levels.
