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.
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.
