Why Choose the ABB E2S/MS 1250 4P Withdrawable Switch-Disconnector?
The ABB E2S/MS 1250, order code 1SDA058868R1, is a high-performance SACE Emax switch-disconnector moving part designed for switching and isolation in demanding low-voltage power distribution systems. This model has a rated current of 1250 A, a four-pole configuration and a withdrawable execution for integration with a compatible Emax fixed part.
As part of the ABB SACE Emax E2S/MS series, the unit combines robust switching capability with the flexibility of a withdrawable design. The MS switch-disconnector configuration is intended primarily for circuit switching and isolation rather than integral overcurrent protection, allowing protection to be coordinated elsewhere in the electrical installation.
With a rated operational voltage of up to 690 V AC, rated insulation voltage of 1000 V and rated short-time withstand current of 65 kA for 1 s, the E2S/MS 1250 is suited to high-current industrial and commercial distribution systems. Its moving-part configuration allows the unit to be withdrawn from the compatible fixed part for isolation, servicing and switchboard maintenance.

- Designed for switching and isolation within compatible Emax switchgear.
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 when required. The ABB E2S/MS 1250 combines this function with the robust SACE Emax platform and high short-time current withstand capability required for demanding low-voltage distribution installations.
The withdrawable moving-part construction enables the switch-disconnector to be moved between operating, test or isolated positions when installed with the appropriate Emax fixed part. This configuration supports maintenance and switchboard servicing while providing a practical solution for high-current distribution systems where operational flexibility is important.
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 installations.
- Four-pole feeder and distribution applications.
