1SDA058920R1 ABB SACE Emax E6H/E/MS 6300 A 3-Pole 750 V DC Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB 1SDA058920R1 Emax E6H/E/MS 6300 Switch-Disconnector?

The ABB 1SDA058920R1 is a SACE Emax E6H/E/MS 6300 three-pole withdrawable switch-disconnector moving part designed for high-current DC switching and isolation. Identified by ABB as E6H/E/MS63003pWMP750VDCnew, it combines a substantial 6300 A current rating with a 750 V DC operational rating and withdrawable construction for compatible SACE Emax switchgear.

The E6H/E/MS configuration is intended for switching and electrical isolation rather than automatic overcurrent protection. Its three-pole arrangement and DC-specific configuration make it suitable for demanding direct-current distribution systems, while the withdrawable moving-part design provides the flexibility required in installations where isolation and maintainability are important.

With a rated uninterrupted current of 6300 A, rated operational voltage of 750 V DC and rated short-time withstand current of 65 kA for 1 s, the E6H/E/MS 6300 is engineered for substantial electrical duties. Its E6 frame and H performance level make it suitable for high-capacity DC power distribution applications.

High-Current DC Switching and Isolation

ABB SACE Emax /MS switch-disconnectors provide controlled switching and electrical isolation for high-current power distribution. The E6H/E/MS configuration is specifically suited to demanding DC applications, allowing the switch-disconnector to perform the switching and isolation function while appropriate protective equipment elsewhere in the system provides the required overcurrent and fault protection.

The 1SDA058920R1 combines a substantial 6300 A current rating with 750 V DC operation and a 65 kA for 1 s short-time withstand rating. Its withdrawable moving-part construction enables integration into compatible draw-out switchgear, supporting isolation and maintenance requirements in high-capacity DC distribution installations.
