1SDA073338R1 ABB E6.2H/f 5000 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2H/f 5000 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker?

The ABB E6.2H/f 5000 Ekip Hi-Touch LSI 4p WMP, order code 1SDA073338R1, is a high-current SACE Emax 2 air circuit breaker moving part engineered for protection, switching and monitoring in demanding low-voltage power-distribution systems. This full-size E6.2H/f configuration combines a 5000 A rated uninterrupted current, four-pole construction and H-level short-circuit performance with ABB's advanced Ekip Hi-Touch LSI electronic protection release.

The Ekip Hi-Touch LSI trip unit provides long-time overload (L), selective short-time short-circuit (S) and instantaneous short-circuit (I) protection. The Hi-Touch platform adds advanced measurement, monitoring and power-management capabilities to the core protection functions, providing detailed electrical information and configurable protection for sophisticated industrial and infrastructure distribution systems.

The E6.2H/f 5000 provides an ultimate short-circuit breaking capacity of 100 kA from 400 to 690 V AC and a rated short-time withstand current of 100 kA for both 1 s and 3 s. Its withdrawable moving-part architecture is designed for use with the corresponding Emax 2 fixed part, while four auxiliary contacts and open/closed breaker-position indication support switchboard monitoring and control.

Advanced Selective Protection and Power Monitoring

Air circuit breakers such as the ABB Emax 2 E6.2H/f protect major low-voltage distribution circuits against overload and short-circuit conditions. The Ekip Hi-Touch LSI release combines long-time, selective short-time and instantaneous protection, allowing engineers to coordinate protection between different levels of the electrical network and minimise unnecessary interruption of healthy circuits.

The combination of a 5000 A continuous-current rating, 100 kA breaking capacity, advanced Hi-Touch functionality and a 100 kA short-time withstand rating makes the 1SDA073338R1 particularly suitable for large industrial and infrastructure switchboards. Its withdrawable architecture further supports maintenance strategies by allowing the moving breaker assembly to be isolated from the separately installed fixed section.

Typical Applications

• Main incoming protection in high-current low-voltage switchboards.
• Industrial power-distribution systems.
• Transformer secondary protection and distribution.
• Generator and power-generation distribution systems.
• Manufacturing and process-industry switchboards.
• Commercial and infrastructure electrical distribution.
• Data centres and continuity-critical power systems.
• High-current feeders requiring advanced selective LSI protection and monitoring.
