1SDA061441R1 ABB E3V-A/MS 1200 1200 A 3-Pole Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB E3V-A/MS 1200 3-Pole Switch-Disconnector Moving Part?

The ABB E3V-A/MS 1200, order code 1SDA061441R1, is a robust three-pole SACE Emax switch-disconnector moving part designed for high-current switching and isolation duties in low-voltage electrical distribution systems. Part of the ABB SACE Emax E3 series, this version combines a 1200 A current rating with a withdrawable moving-part configuration.

The MS switch-disconnector configuration is intended for dependable circuit switching and isolation rather than integral electronic overcurrent protection. It is therefore suitable for coordinated electrical systems where overload and short-circuit protection is provided by separate protective devices while reliable high-current isolation remains essential.

With a 1200 A current rating, three-pole construction and withdrawable (W) moving-part (MP) configuration, the E3V-A/MS 1200 supports efficient switchboard inspection, servicing and replacement. Its robust SACE Emax construction makes it suitable for demanding industrial distribution systems requiring high-current switching, isolation and serviceability.

Reliable High-Current Switching and Isolation

Switch-disconnectors are used to make, carry and isolate electrical circuits within coordinated low-voltage distribution systems. The ABB E3V-A/MS provides a robust switching and isolation function for high-current circuits, allowing sections of an electrical installation to be isolated for operational, inspection or maintenance requirements.

The withdrawable SACE Emax architecture allows the moving part to be separated from its corresponding fixed part, supporting switchboard serviceability and maintenance. As an MS switch-disconnector, the device is intended primarily for switching and isolation, with suitable overload and short-circuit protection provided elsewhere in the coordinated electrical system.

Typical Applications

• Industrial low-voltage distribution switchboards.
• Main circuit switching and isolation.
• Manufacturing and process plants.
• Power distribution centres.
• Commercial and infrastructure electrical systems.
• Switchboards requiring withdrawable high-current isolation devices.
