Why Choose the ABB E4.2H/E12/VF MS 3200 3p FHR?
The ABB E4.2H/E12/VF MS 3200 3p FHR, order code 1SDA121163R1, is a SACE Emax 2/E12/VF MS air switch-disconnector engineered for demanding variable-frequency power applications. Built on the high-performance E4.2H frame, this configuration provides a rated uninterrupted current of 3200 A with three-pole construction and fixed installation.
ABB's Emax 2/E12/VF MS range is specifically designed for variable-frequency applications up to 1200 V, making the 1SDA121163R1 suitable for specialised power-conversion systems where conventional fixed-frequency switching equipment may not meet the application requirements. The device performs switching and isolation duties as part of an appropriately engineered variable-frequency electrical system.
The 1SDA121163R1 uses a fixed (F) execution with orientable rear horizontal (HR) terminals, represented by the FHR designation. ABB specifies phase separators as mandatory for Emax 2/E applications, with phase separators supplied as standard on the fixed version.
Key Advantages
- Purpose-designed for variable-frequency applications up to 1200 V.
- High 3200 A rated uninterrupted current for demanding power systems.
- E4.2H high-performance frame from the ABB SACE Emax 2 platform.
- Three-pole construction for compatible three-phase applications.
- Fixed execution for permanent switchboard integration.
- Orientable rear horizontal terminals provide a practical rear-connection arrangement.
- Phase separators are supplied as standard with the fixed Emax 2/E version.
- ABB-engineered switch-disconnector solution for specialised variable-frequency installations.

Switching and Isolation for Variable-Frequency Power Systems
Variable-frequency power systems can impose different electrical stresses from conventional fixed-frequency networks, requiring switching equipment specifically designed for the application. ABB's SACE Emax 2/E12/VF MS range addresses these requirements with air switch-disconnectors engineered for variable-frequency installations at voltages up to 1200 V.
The 1SDA121163R1 combines a 3200 A current rating with the E4.2H frame, three-pole construction and orientable rear horizontal terminals. As an MS switch-disconnector, its principal function is switching and isolation rather than electronic overcurrent protection, so the complete installation should incorporate the appropriate protective devices and system coordination required by the application.
Typical Applications
- High-power variable-frequency electrical systems.
- Industrial power-conversion installations.
- Variable-frequency drive output and associated distribution systems where the specified switch-disconnector arrangement is required.
- High-current industrial switchboards.
- Power systems requiring a 3200 A three-pole switch-disconnector.
- Installations operating at variable frequencies and voltages up to 1200 V.
- Fixed switchgear requiring rear horizontal terminal connections.
