Why Choose the ABB E1B/MS 1600 1SDA058859R1 Switch-Disconnector?
The ABB 1SDA058859R1 is a genuine SACE Emax E1B/MS 1600 switch-disconnector moving part designed for high-current switching and isolation in low-voltage power distribution systems. Rated at 1600 A, this three-pole device uses a withdrawable configuration to support serviceable and flexible switchboard installations.
The MS designation identifies the SACE Emax switch-disconnector version, intended primarily for circuit switching and isolation rather than automatic overcurrent protection by an integral electronic trip unit. ABB specifies the E1B/MS 1600 withdrawable moving part with a rated uninterrupted current of 1600 A at 40 °C and a short-time withstand current of 42 kA for 1 s.
This configuration is a three-pole withdrawable moving part (W/MP) designed for use with the corresponding compatible SACE Emax fixed part. The withdrawable arrangement enables the moving part to be disconnected and removed from the switchgear for inspection, servicing or replacement, making it well suited to industrial installations where maintainability and controlled isolation are important.

Withdrawable Switching and Isolation for Power Distribution
A switch-disconnector provides controlled switching and circuit isolation without performing the same automatic overcurrent-protection function as a circuit breaker fitted with a protection release. In systems using an MS switch-disconnector, the necessary overload and short-circuit protection must therefore be provided and coordinated elsewhere within the electrical installation.
The ABB E1B/MS 1600 combines this isolation functionality with a withdrawable SACE Emax construction. The moving part can be used with its corresponding fixed section to provide a serviceable switchboard arrangement, while its 42 kA one-second short-time withstand capability supports demanding high-current distribution applications.
Typical Applications
- Low-voltage main distribution switchboards.
- Withdrawable industrial switchgear.
- High-current circuit isolation.
- Main and sectionalising switch applications.
- Manufacturing and process facilities.
- Commercial and infrastructure power distribution.
- Three-phase switching and isolation systems.
- Installations where overcurrent protection is provided by separately coordinated protective equipment.

Frequently Asked Questions
What is the ABB 1SDA058859R1?
The ABB 1SDA058859R1 is a SACE Emax E1B/MS 1600 three-pole withdrawable switch-disconnector moving part designed for high-current switching and isolation in low-voltage power distribution systems.
What is the current rating of the ABB E1B/MS 1600 1SDA058859R1?
The E1B/MS 1600 has a rated uninterrupted current (Iu) of 1600 A at 40 °C.
Is the ABB 1SDA058859R1 fixed or withdrawable?
The 1SDA058859R1 is a withdrawable (W) moving part (MP) designed for use with the corresponding compatible ABB SACE Emax fixed part.
What is the short-time withstand current of the ABB 1SDA058859R1?
ABB specifies a short-time withstand current (Icw) of 42 kA for 1 s for the E1B/MS 1600 withdrawable configuration.
Does the ABB E1B/MS 1600 provide automatic overcurrent protection?
The E1B/MS 1600 is a switch-disconnector intended primarily for switching and isolation rather than automatic overcurrent protection by an integral trip unit. The installation therefore requires appropriately coordinated protective equipment to provide the necessary overload and short-circuit protection.
