Why Choose the ABB E1N/MS 800 4P W MP Switch Disconnector?
The ABB E1N/MS 800 4P W MP, order code 1SDA058942R1, is a robust SACE Emax air switch disconnector moving part designed for switching and isolation in low-voltage electrical distribution systems. Part of the proven ABB New Emax E1 series, this four-pole unit provides a rated uninterrupted current of 800 A and is supplied as the moving part for a withdrawable switch-disconnector installation.
The E1N/MS 800 combines a four-pole withdrawable construction with the serviceability required in industrial switchboards. Its N performance level provides a rated short-time withstand current of 50 kA for 1 s and 36 kA for 3 s, supporting dependable isolation in distribution systems with substantial prospective fault currents.
Rated for operation up to 690 V AC or 250 V DC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E1N/MS 800 provides robust electrical performance for industrial power systems. The withdrawable moving-part format enables the switching unit to be disconnected and withdrawn from its corresponding fixed part for inspection, maintenance or replacement.

Reliable Switching and Isolation for Power Distribution
Switch disconnectors provide controlled switching and isolation of electrical circuits without incorporating the overcurrent protection functions of a conventional circuit breaker. The ABB E1N/MS is therefore suitable for systems where protection is provided separately and a robust switching device is required for operational isolation, maintenance and segregation of distribution circuits.
The withdrawable SACE Emax construction provides an important maintenance advantage because the moving part can be disconnected and withdrawn from its corresponding fixed section. Combined with its 800 A current rating, four-pole configuration and 50 kA one-second withstand capability, the E1N/MS 800 is well suited to industrial, commercial and infrastructure power distribution assemblies.
Typical Applications
- Industrial low-voltage power distribution switchboards.
- Main incoming and distribution isolation.
- Withdrawable switchgear assemblies.
- Industrial plants and manufacturing facilities.
- Commercial and infrastructure power distribution systems.
- Feeder and busbar isolation.
