1SDA073348R1 ABB E6.2V/f 5000 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker

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

The ABB E6.2V/f 5000 Ekip Hi-Touch LSI 4p WMP, order code 1SDA073348R1, is a high-performance SACE Emax 2 withdrawable air circuit breaker moving part designed for protection, switching and advanced monitoring in demanding low-voltage power-distribution systems. Part of the ABB Emax 2 E6.2 full-size range, this four-pole breaker combines a 5000 A rated uninterrupted current, V-level short-circuit performance and an advanced Ekip Hi-Touch LSI electronic protection release.

The integrated 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 extends these core protection functions with advanced measurement, monitoring and power-management capabilities, providing detailed electrical information for sophisticated industrial, infrastructure and critical-power distribution systems.

The E6.2V/f 5000 delivers an ultimate short-circuit breaking capacity of 150 kA at 400/415/440 V AC, 130 kA at 500/525 V AC and 100 kA at 690 V AC. It also provides a rated short-time withstand current of 100 kA for both 1 s and 3 s. Its withdrawable moving-part construction is designed for use with the corresponding Emax 2 fixed part, supporting efficient isolation, inspection and maintenance in critical switchboards.

Advanced Selective Protection and Power Monitoring

Air circuit breakers such as the ABB Emax 2 E6.2V/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, enabling engineers to coordinate protective devices across different levels of the distribution network and minimise unnecessary interruption of healthy circuits.

The combination of a 5000 A continuous-current rating, 150 kA breaking capacity at 400/415/440 V AC, advanced Hi-Touch functionality and a 100 kA short-time withstand rating makes the 1SDA073348R1 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 part.

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.
