Why Choose the ABB E1B/E MS 800 4P 1000V DC F HR Switch Disconnector?
The ABB E1B/E MS 800 4P 1000V DC F HR, order code 1SDA059042R1, is a specialised SACE Emax air switch disconnector designed for high-current switching and isolation in DC power distribution systems. Built on the ABB E1 frame, this four-pole fixed device provides a rated uninterrupted current of 800 A and is engineered for operation at up to 1000 V DC.
The E1B/E MS DC architecture uses its four poles in series to support operation at the full 1000 V DC rating. Its fixed construction and rear horizontal terminals provide a robust arrangement for integration into industrial switchboards and DC busbar systems, while a rated short-time withstand current of 20 kA for 1 s supports demanding distribution and isolation duties.
With a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E1B/E MS 800 provides the electrical characteristics required for elevated-voltage DC installations. The Emax/E MS family is intended for switching and isolation rather than integral overcurrent protection, making it suitable for systems where protective functions are provided by separate coordinated equipment.
Key Advantages

Reliable 1000 V DC Switching and Isolation
ABB developed the Emax/E MS switch-disconnector family for DC applications up to 1000 V DC, including duties such as main isolation and bus-tie switching in industrial DC systems. In the four-pole configuration, the poles are connected in series to achieve the full 1000 V DC operating capability, while three-pole versions of the family are used for applications up to 750 V DC.
The E1B/E MS 800 combines this specialised DC switching architecture with an 800 A continuous-current rating, 20 kA one-second short-time withstand capability and fixed rear-terminal construction. This makes it a practical solution for engineered DC switchboards where reliable circuit isolation, high operating voltage and substantial current-carrying capability are required.
Typical Applications
- Industrial DC distribution systems operating up to 1000 V DC.
- High-current DC main isolation.
- DC bus-tie and busbar switching.
- Fixed DC switchboard assemblies.
- Electrical traction and associated DC power systems.
- Industrial installations requiring reliable high-voltage DC circuit isolation.
