1SDA073289R1 ABB E6.2V 6300 Ekip Hi-Touch LSIG 4p WMP Air Circuit Breaker

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

The ABB E6.2V 6300 Ekip Hi-Touch LSIG 4p WMP, order code 1SDA073289R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection, switching and control in demanding low-voltage power-distribution systems. Part of the advanced ABB Emax 2 E6.2 series, this withdrawable four-pole breaker combines a 6300 A rated current with the high breaking performance of the V version and an advanced Ekip Hi-Touch LSIG electronic protection release.

The integrated Ekip Hi-Touch LSIG trip unit provides long-time overload (L), selective short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. The Hi-Touch platform extends the Ekip electronic protection concept with advanced measurement, monitoring and power-management capabilities, making it particularly suitable for sophisticated electrical distribution systems where protection selectivity and detailed system supervision are important.

The E6.2V 6300 provides an ultimate short-circuit breaking capacity of 150 kA at 400/415 V AC and 100 kA at 690 V AC. Its withdrawable moving-part construction is designed to interface with the corresponding Emax 2 fixed part, while the breaker is supplied with four auxiliary contacts and open/closed position indication for integration into switchboard control and monitoring systems.

Advanced Protection and Monitoring for Critical Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V protect major low-voltage distribution circuits against overloads, short circuits and earth faults. The Ekip Hi-Touch LSIG release continuously supervises electrical conditions and provides separate long-time, short-time, instantaneous and earth-fault protection functions, helping engineers achieve selective protection while reducing unnecessary interruption of unaffected circuits.

The combination of a 6300 A current rating, V-level high breaking performance, advanced Hi-Touch electronic functionality and withdrawable construction makes the 1SDA073289R1 particularly suitable for complex industrial and infrastructure switchboards. Its monitoring capabilities support modern energy-management strategies, while the withdrawable architecture simplifies inspection and servicing of critical power-distribution equipment.
