1SDA061429R1 ABB E3S-A/MS 2500 3-Pole Withdrawable Switch Disconnector Moving Part

Why Choose the ABB E3S-A/MS 2500 3-Pole Switch Disconnector?

The ABB E3S-A/MS 2500, order code 1SDA061429R1, is a robust three-pole switch disconnector moving part designed for high-current switching and isolation in low-voltage electrical distribution systems. As part of the proven ABB SACE Emax E3 series, it combines a 2500 A rated current with withdrawable construction for dependable integration into demanding industrial, commercial and infrastructure switchgear.

The E3S-A/MS configuration is a switch-disconnector version of the Emax platform, intended for applications requiring reliable circuit switching and isolation without an integral electronic overcurrent protection release. The S performance class is engineered for demanding power distribution environments where high short-time current withstand capability and dependable isolation are important.

The 1SDA061429R1 is supplied as a three-pole withdrawable moving part (W MP) for installation with the corresponding ABB SACE Emax fixed part or cradle. Its draw-out construction allows the switching device to be disconnected and removed for inspection, servicing or replacement, while the 2500 A rating makes it suitable for major distribution circuits and other high-current applications.

Reliable Switching and Isolation for Power Distribution

Switch disconnectors such as the ABB E3S-A/MS provide a dependable means of switching and isolating high-current electrical circuits within low-voltage distribution systems. Unlike an automatic circuit breaker equipped with an electronic overcurrent trip release, the MS configuration is primarily intended to perform switching and isolation duties as part of a correctly coordinated electrical protection system.

The withdrawable SACE Emax construction is particularly valuable in switchboards where maintainability and operational flexibility are important. The moving part can be disconnected from the corresponding fixed cradle and removed for servicing, helping simplify inspection and replacement while providing a practical high-current isolation solution for critical power distribution equipment.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• High-current circuit switching and isolation.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical distribution.
• Power distribution centres.
• Transformer and generator distribution assemblies.
• Applications requiring a withdrawable three-pole 2500 A isolation device.
