1SDA104627R1 ABB E6.2H/E9 5000 Ekip Touch LSIG 3p WMP 900V Air Circuit Breaker

Why Choose the ABB E6.2H/E9 5000 Ekip Touch LSIG 3p WMP 900V Air Circuit Breaker?

The ABB 1SDA104627R1 is a high-capacity SACE Emax 2 air circuit breaker (ACB) engineered for protection, control and switching in demanding electrical distribution systems operating at 900 V AC. This E6.2H/E9 model combines a 5000 A rated uninterrupted current, three-pole construction and ABB's Ekip Touch LSIG electronic trip unit for comprehensive protection of high-current industrial, infrastructure and energy distribution networks.

The Ekip Touch LSIG electronic protection trip unit provides long-time, short-time, instantaneous and ground-fault protection. Its touch-based interface supports convenient configuration and monitoring of protection functions, helping engineers coordinate protection and manage high-current distribution systems while safeguarding equipment against overloads, short circuits and earth faults.

Designed as a withdrawable moving part (WMP) for compatible ABB Emax 2 switchgear, the E6.2H/E9 5000 facilitates inspection, servicing and replacement while retaining the fixed chassis within the switchboard. The E6.2H performance level provides an ultimate short-circuit breaking capacity of 75 kA at 900 V AC, delivering substantial fault-interruption capability for high-power installations.

Advanced LSIG Protection for High-Current 900 V Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2H/E9 provide switching and protection for high-current electrical distribution systems where substantial prospective fault currents can occur. The Ekip Touch electronic trip unit monitors circuit conditions and operates the breaker according to configured protection thresholds, helping safeguard busbars, conductors, switchgear and downstream equipment from damaging electrical faults.

The LSIG protection package combines long-time protection against sustained overloads, short-time protection for selective fault coordination, instantaneous protection against severe short circuits and ground-fault protection for earth-fault conditions. Together with its 5000 A current rating, 75 kA breaking capacity at 900 V AC and withdrawable Emax 2 architecture, the 1SDA104627R1 provides a robust solution for critical high-power distribution switchboards.
