1SDA073275R1 ABB E6.2H 6300 Ekip Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2H 6300 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E6.2H 6300 Ekip Touch LSI 4p WMP, order code 1SDA073275R1, is a high-current SACE Emax 2 air circuit breaker moving part designed for protection, switching and isolation in demanding low-voltage power-distribution systems. Part of the ABB Emax 2 E6.2 series, this withdrawable four-pole breaker combines a 6300 A rated continuous current with H-level breaking performance and an intelligent Ekip Touch LSI electronic protection release.

The integrated Ekip Touch LSI trip unit provides long-time overload (L), selective short-time short-circuit (S) and instantaneous short-circuit (I) protection. Its touchscreen interface supports intuitive configuration and monitoring, allowing protection parameters to be adapted to the requirements of major distribution circuits while supporting selective coordination between upstream and downstream protective devices.

The E6.2H 6300 is rated for operation at up to 690 V AC and provides an ultimate short-circuit breaking capacity of 100 kA at 400 V AC. Its withdrawable moving-part configuration connects to a separate fixed chassis section, helping simplify isolation, inspection and maintenance in high-current switchboards while four changeover auxiliary contacts provide breaker-status signalling.

Reliable Selective Protection for High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H protect major low-voltage distribution circuits against overload and short-circuit conditions. The Ekip Touch LSI release continuously monitors current and provides separate long-time, short-time and instantaneous protection functions, allowing engineers to coordinate the breaker with other protective devices and reduce unnecessary interruption of unaffected circuits.

The combination of a 6300 A current rating, 100 kA breaking capability, intelligent electronic protection and withdrawable architecture makes the 1SDA073275R1 particularly suitable for substantial industrial and infrastructure switchboards. The moving part can be isolated from its fixed chassis for servicing, while auxiliary status contacts facilitate integration with switchboard monitoring and control systems.

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.
