Why Choose the ABB E1B/MS 1600 1SDA058858R1 Switch-Disconnector?
The ABB 1SDA058858R1 is a SACE Emax E1B/MS 1600 switch-disconnector designed for isolation and switching duties in low-voltage power distribution systems. Rated at 1600 A, this four-pole fixed device provides a robust solution for installations requiring dependable circuit isolation without an integral overcurrent protection release.
The MS designation identifies the Emax switch-disconnector version, making the 1SDA058858R1 suitable for applications where switching and isolation are required while circuit protection is provided elsewhere in the electrical system. Its four-pole configuration enables simultaneous switching of all four conductors in suitable three-phase distribution arrangements.
This configuration is a fixed (F) execution with horizontal rear (HR) terminals, providing a practical connection arrangement for compatible switchboards and distribution assemblies. As part of the ABB New Emax family, the E1B/MS 1600 combines high-current switching capability with the mechanical construction of the SACE Emax platform.

High-Current Switching and Isolation
A switch-disconnector provides a means of switching and isolating an electrical circuit without performing the same automatic overcurrent-protection function as a circuit breaker equipped with a protection release. This makes switch-disconnectors useful where the installation requires a high-current isolation device while overload and short-circuit protection are coordinated through separate protective equipment.
The ABB E1B/MS 1600 applies this functionality to the SACE Emax platform. Its 1600 A, four-pole fixed configuration and horizontal rear connections make the 1SDA058858R1 suitable for integration into substantial low-voltage switchboards where reliable switching, isolation and straightforward rear connections are required.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial electrical distribution systems.
- Commercial building power distribution.
- High-current circuit isolation.
- Main and sectionalising switch applications.
- Manufacturing and process facilities.
- Four-pole switching applications.
- Systems where overcurrent protection is provided by separate protective equipment.

Frequently Asked Questions
What is the ABB 1SDA058858R1?
The ABB 1SDA058858R1 is a SACE Emax E1B/MS 1600 four-pole fixed switch-disconnector with horizontal rear terminals, designed for switching and isolation in low-voltage power distribution systems.
What is the current rating of the ABB E1B/MS 1600 1SDA058858R1?
The device is rated at 1600 A, making it suitable for high-current low-voltage distribution and isolation applications.
What does MS mean on the ABB E1B/MS 1600?
The MS designation identifies the switch-disconnector version of the ABB SACE Emax device, intended primarily for switching and isolation rather than automatic overcurrent protection by an integral trip unit.
Is the ABB 1SDA058858R1 fixed or withdrawable?
The ABB 1SDA058858R1 is a fixed (F) four-pole switch-disconnector with horizontal rear (HR) terminals.
Does the ABB E1B/MS 1600 provide automatic overcurrent protection?
The E1B/MS 1600 is a switch-disconnector intended for switching and isolation duties rather than operation as a circuit breaker with an integral overcurrent protection release. The electrical installation must therefore provide the required circuit protection through appropriately coordinated protective equipment.
