Why Choose the ABB E1N-A/MS 800 3-Pole Switch Disconnector?
The ABB E1N-A/MS 800, order code 1SDA061377R1, is a robust three-pole switch disconnector moving part designed for switching and isolation in high-current low-voltage electrical distribution systems. As part of the proven ABB SACE Emax E1 series, it provides an 800 A frame rating and dependable isolation functionality for industrial, commercial and infrastructure switchgear.
The E1N-A/MS configuration is a switch-disconnector version of the Emax platform, intended for applications where reliable circuit switching and isolation are required without an integral electronic overcurrent protection release. Its E1N performance class provides a 50 kA rated short-time current at 480 V, supporting demanding low-voltage distribution installations.
The 1SDA061377R1 is supplied as a three-pole withdrawable moving part (W MP) for installation with the corresponding Emax fixed part or cradle. This draw-out construction allows the switching device to be isolated and removed for inspection, servicing or replacement, helping simplify maintenance in critical electrical distribution systems.

Reliable Switching and Isolation for Power Distribution
Switch disconnectors such as the ABB E1N-A/MS provide a dependable means of switching and isolating electrical circuits within low-voltage distribution systems. Unlike an automatic circuit breaker equipped with an electronic trip release, the MS configuration is primarily intended to perform switching and isolation duties as part of a properly coordinated electrical protection system.
The withdrawable SACE Emax construction is particularly useful 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 facilitate inspection and maintenance while providing clear separation from the main power connections.
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 isolation device.
