ABB 1SDA071735R1 SACE Emax 2 E4.2V fixed four-pole 2000 A air circuit breaker with an Ekip Touch LSI electronic trip unit for high-performance low-voltage power distribution protection.
£11,459.90
The ABB 1SDA071735R1 is a high-performance SACE Emax 2 E4.2V air circuit breaker (ACB) rated at 2000 A, designed for protection and switching in demanding low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, this fixed four-pole circuit breaker combines exceptionally high short-circuit performance with an intelligent Ekip Touch LSI electronic trip unit.
The E4.2V 2000 incorporates the Ekip Touch LSI electronic release, providing long-time overload, short-time selective and instantaneous short-circuit protection. Its touchscreen interface supports intuitive configuration, measurement and monitoring, helping operators manage protection settings and electrical distribution systems efficiently.
With a rated uninterrupted current of 2000 A, a rated operational voltage up to 690 V AC and an ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC and 100 kA at 500–690 V AC, the E4.2V is engineered for installations with very high prospective fault currents. This version is a fixed, four-pole breaker with rear flat horizontal terminals, making it suitable for integration into high-performance low-voltage switchboards.
ABB SACE Emax 2 air circuit breakers protect low-voltage distribution networks against overload and short-circuit conditions while providing dependable switching and isolation. The E4.2V performance level delivers exceptionally high breaking capacity, making it particularly suitable for installations where substantial prospective fault currents require robust interruption capability.
The Ekip Touch LSI release provides long-time overload (L), short-time selective (S) and instantaneous short-circuit (I) protection. Adjustable electronic protection settings and the touchscreen interface support selective coordination and precise configuration within complex industrial, commercial and infrastructure distribution networks.
