Why Choose the ABB 1SDA058952R1 Emax E2N/MS 1600 Switch-Disconnector?
The ABB 1SDA058952R1 is a SACE Emax E2N/MS 1600 four-pole fixed switch-disconnector designed for dependable switching and electrical isolation in low-voltage power distribution systems. Identified by ABB as E2N/MS 1600 4p F HR new, it combines a 1600 A current rating with a fixed four-pole construction and rear horizontal terminals.
The E2N/MS configuration is intended for switching and isolation duties rather than automatic overcurrent protection. Its four-pole arrangement enables switching across four conductors, while the fixed installation and rear flat horizontal terminal arrangement make it suitable for permanent integration into compatible industrial and commercial switchboards.
With a rated operational voltage of 690 V AC and 250 V DC, the E2N/MS 1600 provides robust electrical performance for demanding distribution applications. It offers a rated short-time withstand current of 55 kA for 1 s and 42 kA for 3 s, together with a 1000 V insulation voltage and 12 kV impulse withstand voltage.

Fixed High-Current Switching and Isolation
ABB SACE Emax /MS switch-disconnectors are designed to provide controlled switching and electrical isolation within low-voltage distribution systems. The E2N/MS 1600 performs these functions without the electronic overcurrent release associated with an automatic Emax circuit breaker, allowing protective functions to be coordinated separately within the electrical installation.
The fixed four-pole configuration of the 1SDA058952R1 is particularly suited to permanent switchboard installations requiring substantial current-carrying capability. Its rear horizontal terminals facilitate compatible busbar connections, while its 55 kA for 1 s short-time withstand rating supports use in distribution systems with demanding prospective fault-current conditions.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Four-pole switching and electrical isolation.
- Fixed high-current switchgear assemblies.
- 1600 A feeder switching and isolation.
- Transformer secondary distribution systems.
- Manufacturing and process industry installations.
- Commercial and infrastructure power distribution systems.
