Why Choose the ABB 1SDA125910R1 E4.3V/MS 2000 Emax 3 Switch-Disconnector?
The ABB 1SDA125910R1, designated E4.3V/MS 2000 3p FHR, is a high-performance SACE Emax 3 switch-disconnector designed for switching and isolation in demanding low-voltage power distribution systems. Part of the ABB Emax 3 range, this E4.3V/MS configuration combines a 2000 A rated current with a robust three-pole fixed construction.
Unlike an Emax 3 circuit breaker equipped with an electronic trip unit, the MS switch-disconnector version is intended primarily for circuit switching and isolation. It provides a dependable means of disconnecting high-current electrical circuits and is suited to switchboards where overcurrent protection is provided separately by upstream or downstream protective devices.
The ABB 1SDA125910R1 uses the E4.3 frame with the high-performance V class, a three-pole configuration and fixed execution with horizontal rear terminals. These characteristics make it suitable for main distribution, bus-section and isolation duties in industrial and infrastructure power systems.

Reliable High-Current Switching and Isolation
Switch-disconnectors provide a defined means of switching and isolating electrical circuits without incorporating the complete overcurrent-protection functionality of an air circuit breaker with a trip unit. This makes them particularly useful in distribution systems where protective functions are provided elsewhere but dependable high-current isolation is still required.
The ABB E4.3V/MS platform brings Emax 3 switching technology to these applications in a fixed three-pole format. With its 2000 A current rating and horizontal rear terminals, the 1SDA125910R1 is suited to integration into high-current switchboards, busbar systems and industrial distribution assemblies requiring robust switching and isolation.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial high-current power distribution systems.
- Main circuit isolation and switching.
- Bus-section and bus-coupler applications.
- Commercial and infrastructure electrical installations.
- Switchgear assemblies with separate overcurrent protection.

Frequently Asked Questions
What is the ABB 1SDA125910R1 used for?
The ABB 1SDA125910R1 is an Emax 3 switch-disconnector designed for high-current switching and electrical isolation in low-voltage power distribution systems.
What is the rated current of the ABB E4.3V/MS 2000?
The ABB E4.3V/MS configuration has a rated current of 2000 A.
How many poles does the ABB 1SDA125910R1 have?
The ABB 1SDA125910R1 is a three-pole switch-disconnector for compatible three-phase power-distribution systems.
Does the ABB E4.3V/MS 2000 include an electronic trip unit?
No. The MS configuration is a switch-disconnector intended for switching and isolation rather than integral overcurrent protection, so appropriate circuit protection must be provided elsewhere in the electrical system.
What installation configuration does the ABB 1SDA125910R1 use?
The ABB 1SDA125910R1 uses a fixed three-pole configuration with horizontal rear terminals for integration into compatible low-voltage switchgear.
