Why Choose the ABB E6.2H/f 5000 Ekip Dip LI 4p F HR Air Circuit Breaker?
The ABB E6.2H/f 5000 Ekip Dip LI 4p F HR, order code 1SDA071981R1, is a high-current four-pole fixed air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. With a rated uninterrupted current of 5000 A, it provides dependable protection for major electrical installations, switchboards and industrial distribution networks.
This E6.2H/f breaker incorporates an Ekip Dip LI electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. The electronic release enables effective protection of high-current distribution circuits while the Emax 2 platform combines high breaking performance with flexible integration into low-voltage switchgear.
The breaker is supplied in a fixed, four-pole configuration with full-size neutral and rear horizontal terminals. Its H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at common system voltages up to 690 V AC, together with a 100 kA / 1 s short-time withstand capability for selective power distribution applications.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB Emax 2 E6.2H/f protect major low-voltage distribution circuits against damaging overcurrents and short circuits while providing a controllable switching point within the electrical installation. Their high breaking and withstand capabilities make them particularly suitable for main distribution boards and other locations where substantial prospective fault currents can occur.
The Ekip Dip LI electronic trip unit continuously supports circuit protection through adjustable long-time overload protection and instantaneous short-circuit protection. Combined with the E6.2H frame's high current and fault-interruption capability, this makes the breaker suitable for reliable protection of critical industrial and infrastructure power systems.
Typical Applications
- Main low-voltage switchboards and distribution boards.
- Industrial power distribution systems.
- Large manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer secondary and main incoming circuits.
- High-current feeder and distribution protection.
- Power systems requiring high short-circuit breaking and withstand capability.
