Why Choose the ABB E1B/MS 1600 3P Fixed Switch-Disconnector?
The ABB E1B/MS 1600, order code 1SDA058857R1, is a robust SACE Emax switch-disconnector designed for high-current isolation and switching in low-voltage power distribution systems. This model combines a 1600 A frame rating with a three-pole fixed configuration and horizontal rear terminals, providing a dependable solution for industrial and commercial switchboards.
As part of the ABB SACE Emax E1B/MS series, this switch-disconnector is intended for applications where reliable circuit isolation and switching are required without an integral overcurrent protection release. The MS execution provides the switching and isolation functions of the Emax platform while allowing circuit protection to be coordinated using suitable upstream or external protective devices.
The E1B/MS1600 3P F HR configuration features three poles, fixed installation and horizontal rear (HR) terminals. Its fixed format is particularly suitable for switchboards where permanent installation is preferred, while the rear terminal arrangement facilitates connection to busbars and other high-current distribution conductors.
Key Advantages
- Heavy-duty 1600 A SACE Emax switch-disconnector.
- Three-pole configuration for three-phase power distribution systems.
- Fixed installation for permanent switchboard integration.
- Horizontal rear terminals support practical busbar connections.
- Provides reliable switching and isolation of high-current electrical circuits.
- Part of the established ABB SACE Emax low-voltage switching platform.

Reliable High-Current Switching and Isolation
Switch-disconnectors provide a means of switching and isolating electrical circuits so that downstream equipment can be safely separated from the supply when required. Unlike an Emax circuit breaker fitted with an electronic protection release, an MS switch-disconnector is primarily intended to perform switching and isolation, with appropriate circuit protection provided elsewhere in the electrical installation.
The ABB E1B/MS 1600 combines this isolation capability with the robust mechanical platform of the SACE Emax range. Its three-pole fixed construction and horizontal rear terminals make it particularly suitable for integration into high-current low-voltage switchboards and power distribution assemblies.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- High-current circuit isolation.
- Manufacturing and process plant switchgear.
- Commercial and infrastructure electrical installations.
- Busbar and feeder switching applications.
