Why Choose the ABB 1SDA058874R1 Emax E2S/MS 2000 Switch-Disconnector?
The ABB 1SDA058874R1 is a SACE Emax E2S/MS 2000 four-pole fixed switch-disconnector designed for high-current switching and isolation in low-voltage power distribution systems. Identified as E2S/MS 2000 4P F HR, this configuration combines a 2000 A current rating with fixed installation and rear horizontal terminals.
The E2S/MS configuration is intended for switching and isolation rather than automatic overcurrent protection. Its four-pole arrangement enables simultaneous switching across four conductors, making it suitable for power distribution systems where the neutral conductor also needs to be switched alongside the three phase conductors.
With a rated uninterrupted current of 2000 A, rated operational voltage of 690 V AC and an S short-circuit performance level, the E2S/MS 2000 provides robust electrical withstand characteristics. Its fixed construction and rear horizontal terminals make it particularly suitable for permanent installation in industrial switchboards and high-current distribution assemblies.

High-Current Switching and Isolation with Emax E2S/MS
ABB SACE Emax switch-disconnectors provide controlled switching and isolation in high-current power distribution systems. The /MS configuration is intended for switching and disconnection duties rather than automatic overcurrent protection, allowing the device to form part of a coordinated electrical system where fault protection is provided by other suitable protective equipment.
The E2S/MS 2000 provides a substantial 65 kA short-time withstand current for 1 s and 50 kA for 3 s. Combined with its 2000 A rating, four-pole construction and rear horizontal terminals, this makes the 1SDA058874R1 well suited to permanent installation in high-capacity industrial distribution switchboards.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Four-pole power switching and isolation.
- Fixed high-current switchgear assemblies.
- Transformer secondary distribution systems.
- High-current feeder isolation.
- Manufacturing and process industry installations.
- Commercial and infrastructure power distribution.
