Why Choose the ABB E6H/E/MS 5000 3P Withdrawable 750 V DC Switch-Disconnector?
The ABB E6H/E/MS 5000, order code 1SDA058918R1, is a heavy-duty SACE Emax DC switch-disconnector moving part designed for high-current switching and isolation in demanding direct-current power distribution systems. It combines a 5000 A rated uninterrupted current with a 750 V DC operating voltage and three-pole withdrawable construction.
Part of the ABB SACE Emax E6H/E/MS range, this device is intended for switching and isolation rather than integral overcurrent protection. Its 65 kA short-time withstand current for 1 s provides the robust electrical performance required in high-power DC installations where protection is coordinated separately.
The E6H/E/MS 5000 3P W MP 750V DC configuration is supplied as a withdrawable moving part (W MP) for use with the appropriate Emax fixed part. This arrangement provides convenient disconnection and withdrawal for inspection, servicing and maintenance of critical high-current DC switchboards.

High-Current DC Switching and Isolation
High-power DC distribution requires switching equipment engineered specifically for direct-current operating conditions. The ABB E6H/E/MS 5000 provides controlled switching and isolation at up to 750 V DC, with a 5000 A continuous current capability suited to large industrial and infrastructure power systems.
Its withdrawable moving-part construction provides additional service flexibility in critical installations. When paired with the appropriate Emax fixed part, the switching unit can be disconnected and withdrawn for inspection or maintenance while providing the robust electrical characteristics expected from the ABB SACE Emax platform.
Typical Applications
- High-current DC distribution switchboards.
- Industrial DC power systems.
- Large battery and energy-storage distribution systems.
- DC feeder switching and isolation.
- Marine and transportation DC electrical systems.
- Infrastructure and process-industry DC installations.
