1SDA058907R1 ABB E6H/MS 4000 3P Withdrawable Switch-Disconnector

Why Choose the ABB E6H/MS 4000 3P Withdrawable Switch-Disconnector?

The ABB E6H/MS 4000, order code 1SDA058907R1, is a heavy-duty SACE Emax switch-disconnector moving part designed for high-current switching and isolation in demanding low-voltage power distribution systems. This model combines a 4000 A rated current with a three-pole withdrawable configuration for integration with the appropriate ABB Emax fixed part.

As part of the ABB SACE Emax E6H/MS series, the unit provides robust switching and isolation functionality without an integral electronic overcurrent protection release. The H performance class is intended for demanding installations requiring high short-circuit performance, while the MS configuration provides a non-automatic switching and isolation solution for systems where circuit protection is coordinated separately.

The E6H/MS 4000 3P W MP configuration features three poles and a withdrawable moving part (W MP). Its high-current E6 frame and withdrawable construction make it particularly suitable for large switchboards where reliable isolation, operational flexibility and convenient servicing are important.

Reliable High-Current Switching and Isolation

Switch-disconnectors provide controlled switching and isolation of electrical circuits, allowing downstream equipment to be separated from the supply for operational or maintenance purposes. The ABB E6H/MS 4000 combines this function with the robust SACE Emax platform, providing a purpose-designed solution for high-current distribution systems where dependable isolation is essential.

The withdrawable moving-part construction provides additional flexibility for critical switchboards. When installed with the appropriate Emax fixed part, the E6H/MS unit can be withdrawn from its connected position for isolation, inspection or servicing, helping simplify maintenance of large power distribution assemblies.

Typical Applications

• Large low-voltage main distribution switchboards.
• Industrial power distribution systems.
• High-current circuit switching and isolation.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical installations.
• Three-phase feeder and busbar switching applications.
