1SDA073378R1 ABB E6.2V/f 6300 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2V/f 6300 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker?

The ABB E6.2V/f 6300 Ekip Hi-Touch LSI 4p WMP, order code 1SDA073378R1, is a high-performance four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Designed for very high-current low-voltage distribution systems, it combines a rated uninterrupted current of 6300 A with the advanced Ekip Hi-Touch LSI electronic trip unit for long-time overload, short-time selective short-circuit and instantaneous short-circuit protection.

The E6.2V/f full-size platform is engineered for critical switchboards requiring exceptionally high fault-clearing performance. Its V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC, while a rated short-time withstand current of 100 kA for 1 s supports selective coordination in complex industrial and infrastructure power networks.

The Ekip Hi-Touch release provides advanced protection, measurement and monitoring functionality through an intuitive interface, giving operators greater visibility and control over critical electrical systems. The withdrawable moving-part architecture enables the breaker to be used with the appropriate ABB Emax 2 fixed part, supporting efficient inspection, servicing and replacement where continuity of service is important.

Advanced Protection for High-Fault-Level Power Distribution

The ABB Emax 2 E6.2V/f platform is designed for electrical systems where exceptionally high continuous current and fault-clearing performance are required. Combining a 6300 A current rating, 150 kA ultimate short-circuit breaking capacity at 440 V AC and 100 kA short-time withstand capability, this breaker is particularly suited to main incomers, transformer secondary circuits, bus couplers and other critical high-current circuits.

The Ekip Hi-Touch LSI electronic release combines adjustable long-time overload, short-time selective and instantaneous short-circuit protection with advanced monitoring functionality. Together with the Emax 2 withdrawable architecture, this provides a powerful protection solution for installations where electrical selectivity, system visibility, high availability and maintainability are key requirements.
