Why Choose the ABB E1B/E MS 800 3P 750V DC F HR Switch Disconnector?

The ABB E1B/E MS 800 3P 750V DC F HR, order code 1SDA059041R1, 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 three-pole device provides a rated uninterrupted current of 800 A and a rated operational voltage of 750 V DC.

This E1B/E MS configuration combines a fixed installation with rear flat horizontal terminals, providing a robust arrangement for integration into industrial switchboards and engineered DC busbar systems. Its B performance level and rated short-time withstand current of 20 kA for 1 s provide dependable withstand capability for demanding DC 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 is purpose-designed for elevated-voltage DC applications. ABB Emax switch disconnectors retain the overall architecture and accessory possibilities of the corresponding air circuit-breaker platform while operating without an overcurrent trip unit, allowing circuit protection to be provided separately.

Key Advantages

  • 800 A rated uninterrupted current for substantial DC power distribution duties.
  • Purpose-designed for operation at 750 V DC.
  • Three-pole construction configured for high-voltage DC switching and isolation.
  • Fixed installation provides a robust permanent switchboard solution.
  • Rear flat horizontal terminals support efficient connection to engineered busbar systems.
  • 20 kA short-time withstand current for 1 s supports demanding distribution applications.

Key Features

  • ABB SACE Emax E1B/E MS series.
  • 800 A rated uninterrupted current.
  • 750 V DC rated operational voltage.
  • Three-pole (3P) construction.
  • Fixed (F) installation version.
  • Rear flat horizontal (HR) terminal arrangement.
  • 1000 V rated insulation voltage.
  • 12 kV rated impulse withstand voltage.
  • 20 kA rated short-time withstand current.
  • IP30 front-side degree of protection.

Reliable 750 V DC Switching and Isolation

The ABB E1B/E MS 800 is engineered specifically for DC installations requiring dependable switching and isolation at operating voltages up to 750 V DC. Its 1000 V insulation rating, three-pole architecture and 800 A continuous-current capability make it suitable for substantial industrial DC distribution systems where robust circuit segregation is essential.

The fixed E1 construction and rear flat horizontal connection arrangement provide a practical interface for high-current DC busbars. A 20 kA one-second short-time withstand rating and DC-23A utilisation capability support demanding switching duties, while optional motor operation and voltage-release accessories allow the switch disconnector to be incorporated into engineered control and isolation schemes.

Typical Applications

  • Industrial DC distribution systems operating up to 750 V DC.
  • High-current DC main incoming isolation.
  • DC feeder and busbar isolation.
  • Fixed low-voltage switchboard assemblies.
  • Industrial plants and manufacturing facilities with centralised DC systems.
  • Battery-backed and other engineered DC power distribution installations.
