Why Choose the ABB E6.2V/f 5000 Ekip Hi-Touch LSI 4p FHR Air Circuit Breaker?
The ABB E6.2V/f 5000 Ekip Hi-Touch LSI 4p FHR, order code 1SDA071998R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution, it combines a substantial 5000 A rated uninterrupted current with a fully rated fourth pole and exceptional short-circuit performance for industrial, commercial and infrastructure switchboards.
This Emax 2 circuit breaker incorporates the advanced Ekip Hi-Touch LSI electronic trip unit, providing long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. The LSI protection functions support accurate coordination between upstream and downstream protective devices, helping isolate faults selectively while maintaining continuity elsewhere in complex electrical distribution networks.
The E6.2V/f 5000 is a fixed four-pole breaker with a fully rated fourth pole and rear horizontal terminals. The V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 440 V AC together with a rated short-time withstand current of 100 kA for 1 s, making it particularly suitable for high-current, high-fault-level main distribution systems.
Key Advantages
- Very high 5000 A rated uninterrupted current for major low-voltage distribution systems.
- Four-pole configuration with a fully rated fourth pole for demanding four-wire electrical networks.
- Advanced Ekip Hi-Touch LSI electronic trip unit for sophisticated overcurrent protection.
- Long-time, short-time and instantaneous protection supports effective selective coordination.
- Exceptional 150 kA ultimate short-circuit breaking capacity at 440 V AC.
- 100 kA short-time withstand current for 1 s supports high-fault-level selective distribution systems.
- Fixed installation for permanent integration into low-voltage switchboards.
- Rear horizontal terminals facilitate connection to high-current busbar systems.

High-Fault-Level Selective Protection with a Fully Rated Fourth Pole
Air circuit breakers such as the ABB SACE Emax 2 E6.2V/f provide protection, switching and isolation for high-current low-voltage electrical networks. The fully rated four-pole configuration is particularly suited to four-wire distribution systems where the fourth pole requires full current-carrying capability, while the high V-level breaking performance supports installations with substantial prospective fault currents.
The Ekip Hi-Touch LSI trip unit combines long-time overload, short-time selective and instantaneous short-circuit protection. Together with the breaker's 5000 A current rating, 150 kA ultimate breaking capacity at 440 V AC and 100 kA short-time withstand capability, the 1SDA071998R1 provides a robust solution for critical distribution systems requiring very high current capacity, advanced electronic protection and effective fault selectivity.
Typical Applications
- Industrial low-voltage main distribution switchboards.
- Manufacturing plants and large production facilities.
- Transformer protection and distribution systems.
- Generator and critical power distribution systems.
- Data centres and high-availability infrastructure.
- Utilities and major infrastructure installations.
- High-fault-level incoming supply protection.
- Four-wire distribution systems requiring a fully rated fourth pole and selective LSI protection.
