Why Choose the ABB E6.2H 5000 Ekip Dip LI 4p FHR Air Circuit Breaker?
The ABB E6.2H 5000 Ekip Dip LI 4p FHR, order code 1SDA071891R1, is a high-current four-pole SACE Emax 2 air circuit breaker designed for protection and switching in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax 2 E6.2 series, this fixed breaker combines a 5000 A rated uninterrupted current with the reliable Ekip Dip LI solid-state electronic trip unit.
The E6.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA, making the breaker suitable for installations with substantial prospective fault currents. Its Ekip Dip LI release provides long-time overload and instantaneous short-circuit protection, with the overload setting adjustable across 2000–5000 A and the instantaneous threshold extending across 7500–75000 A.
This model is a fixed four-pole air circuit breaker equipped with rear horizontal (FHR) terminals, four auxiliary contacts and open/closed breaker-position indication. The combination of a 5000 A E6.2 frame, high breaking capacity and straightforward electronic LI protection makes the 1SDA071891R1 particularly suitable for main switchboards and other high-capacity industrial and infrastructure distribution systems.
