Why Choose the ABB E3V/MS 800 4P Fixed Switch-Disconnector?
The ABB E3V/MS 800, order code 1SDA058878R1, is a high-performance SACE Emax switch-disconnector designed for switching and isolation in demanding low-voltage power distribution systems. This model combines an 800 A rated uninterrupted current with a four-pole fixed configuration and horizontal rear terminals for integration into industrial, commercial and infrastructure switchboards.
As part of the ABB SACE Emax E3V/MS series, the unit provides robust switching and isolation without an integral electronic overcurrent protection release. Its V performance level provides a high short-time withstand capability, making it suitable for power distribution systems where substantial prospective fault currents may be present and circuit protection is coordinated using appropriate external protective devices.
The E3V/MS 800 4P F HR configuration features four poles, fixed (F) installation and horizontal rear (HR) terminals. With a rated operational voltage up to 690 V AC and a rated short-time withstand current of 85 kA for 1 s, it provides dependable high-current isolation within compatible low-voltage 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 for operational or maintenance purposes. The ABB E3V/MS 800 combines this function with the robust SACE Emax platform and a high short-time current withstand capability suited to demanding power distribution installations.
The four-pole configuration allows simultaneous switching of the three phase conductors and neutral where required by the system design. Its fixed construction and horizontal rear terminals make the E3V/MS 800 particularly suitable for permanent switchboard installations with rear busbar connections.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- High-current circuit switching and isolation.
- Four-pole three-phase and neutral distribution systems.
- Manufacturing and process plant switchgear.
- Commercial and infrastructure electrical installations.
