Why Choose the ABB 1SDA126033R1 E4.3V/MS 2000 Emax 3 Switch-Disconnector?
The ABB 1SDA126033R1, designated E4.3V/MS 2000 4p WMP, is a high-current SACE Emax 3 switch-disconnector moving part designed for switching and isolation duties in demanding low-voltage power distribution systems. This E4.3V/MS configuration combines a 2000 A rated current with a four-pole withdrawable construction.
As an MS switch-disconnector, the device is intended primarily for circuit switching and electrical isolation rather than integral electronic overcurrent protection. It is therefore suitable for distribution architectures where the required overload and short-circuit protection is provided by separate protective devices within the electrical system.
The ABB 1SDA126033R1 uses the E4.3 frame with the V performance level and is supplied as a four-pole withdrawable moving part for use with the appropriate Emax 3 fixed part. Its withdrawable construction supports convenient isolation and servicing in high-current switchboards while the four-pole arrangement accommodates systems requiring neutral switching.
Key Advantages
- High-current ABB SACE Emax 3 switch-disconnector for low-voltage distribution systems.
- 2000 A rated current for demanding power-distribution applications.
- Four-pole configuration for compatible three-phase systems with neutral.
- Withdrawable moving-part construction supports convenient isolation and maintenance.
- V performance level within the Emax 3 E4.3 platform.
- Designed specifically for high-current switching and circuit isolation duties.
- Suitable for switchboards where overcurrent protection is provided separately.
- ABB Emax 3 architecture supports integration into modern industrial and infrastructure switchgear.
Key Features

- Designed for use with the appropriate Emax 3 fixed part.
- Suitable for high-current low-voltage switchgear assemblies.
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 equipped with an electronic trip unit. This makes the E4.3V/MS suitable for distribution systems where protective functions are implemented separately but dependable high-current switching and isolation remain essential.
The withdrawable Emax 3 construction allows the moving part to be separated from the associated fixed part for operational isolation and servicing. With its 2000 A rating and four-pole configuration, the 1SDA126033R1 is well suited to industrial, commercial and infrastructure distribution systems requiring robust switching of three-phase circuits with neutral.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial high-current power distribution systems.
- Main circuit switching and electrical isolation.
- Three-phase systems requiring neutral-pole switching.
- Bus-section and bus-coupler applications.
- Switchgear assemblies with separate overcurrent protection.
