1SDA073105R1 ABB E4.2V 2500 Ekip Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E4.2V 2500 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E4.2V 2500 Ekip Touch LSI 4p WMP, order code 1SDA073105R1, is a high-performance four-pole air circuit breaker moving part designed for protection, control and monitoring in demanding low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, it combines a 2500 A rated uninterrupted current with the intelligent Ekip Touch LSI electronic trip unit.

The Ekip Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Its colour touchscreen interface enables intuitive configuration and access to operating information, while the adjustable protection functions support coordination and selectivity across complex industrial and infrastructure electrical networks.

This E4.2V configuration features a 2500 A rated uninterrupted current, four-pole construction and a rated operational voltage up to 690 V AC. The high-performance V breaking-capacity level provides an ultimate short-circuit breaking capacity of 150 kA at 400 V AC and a rated short-time withstand current of 100 kA for 1 s, while the withdrawable moving-part construction supports efficient inspection and maintenance.

Advanced LSI Protection for High-Current Distribution

The ABB Ekip Touch LSI electronic trip unit provides adjustable protection against overload and both delayed and instantaneous short-circuit conditions. Its touchscreen interface supports intuitive configuration and monitoring, while the short-time protection function enables coordination with downstream protective devices to improve selectivity throughout the electrical distribution system.

The E4.2V frame is engineered for installations requiring exceptionally high fault-interruption performance. Its combination of 150 kA ultimate breaking capacity and 100 kA short-time withstand capability provides robust protection for high-power networks, while the withdrawable construction allows the moving part to be removed from its corresponding fixed part for efficient servicing and maintenance.
