Why Choose the ABB 1SDA058861R1 Emax E1N/MS 1600 Switch-Disconnector?
The ABB 1SDA058861R1 is a SACE Emax E1N/MS 1600 three-pole fixed switch-disconnector designed for high-current switching and isolation in low-voltage power distribution systems. Identified by ABB as E1N/MS 1600 3p F HR new, this configuration combines a 1600 A current rating with a fixed installation and rear horizontal terminals.
The E1N/MS belongs to ABB's Emax switch-disconnector range and differs from an automatic circuit breaker by the absence of an overcurrent trip unit. It is intended primarily for switching and isolation duties and can be used in AC-23A applications in accordance with IEC 60947-3, making it suitable for switching motor loads and other highly inductive loads as well as general power distribution isolation.
With a rated uninterrupted current of 1600 A, rated operational voltage of 690 V AC and N short-circuit performance level, the E1N/MS 1600 provides robust electrical withstand capability. Its fixed construction and rear horizontal terminal arrangement make it well suited to permanent installation within compatible industrial switchboards and distribution assemblies.

High-Current Switching and Isolation with Emax E1N/MS
ABB SACE Emax switch-disconnectors are derived from the corresponding Emax circuit-breaker platform while omitting the overcurrent trip unit. The /MS designation identifies the switch-disconnector version, providing controlled switching and isolation while retaining the overall Emax construction and compatibility with appropriate accessories.
The E1N/MS 1600 provides a 50 kA short-time withstand current for 1 s, allowing it to withstand substantial prospective fault current while an associated protective device performs fault interruption. Its fixed three-pole construction and rear horizontal connections provide a practical configuration for permanent installation in industrial power distribution switchboards.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Three-phase switching and isolation.
- Fixed switchgear assemblies.
- High-current feeder isolation.
- Motor and inductive-load switching applications.
- Manufacturing and process industry distribution systems.
- Commercial and infrastructure power distribution.
