Why Choose the ABB E4.2V/MS 4000 3p F HR Switch-Disconnector?
The ABB E4.2V/MS 4000 3p F HR, order code 1SDA073423R1, is a high-capacity 4000 A three-pole fixed switch-disconnector from the ABB SACE Emax 2 range, designed for dependable switching and isolation in demanding low-voltage power distribution systems.
As an E4.2V/MS switch-disconnector, the device is intended for high-current switching and isolation rather than automatic overload and short-circuit protection. It is therefore suited to installations where protection is provided by appropriately coordinated protective devices elsewhere in the electrical system.
The E4.2V/MS combines a rated uninterrupted current of 4000 A with a rated short-time withstand current of 100 kA for 1 s. Its three-pole fixed construction and rear horizontal terminals provide a robust arrangement for integration into high-current industrial, infrastructure and commercial switchboards.
Key Advantages
- High-capacity 4000 A switch-disconnector for demanding low-voltage systems.
- Reliable switching and isolation for three-phase power distribution.
- Three-pole configuration for high-current applications.
- High 100 kA short-time withstand current for 1 s.
- Designed for applications up to 690 V AC.
- Fixed construction for permanent switchboard installations.
- Rear horizontal terminals support practical busbar and conductor arrangements.
- Part of the robust ABB SACE Emax 2 switching platform.

High-Current Switching and Isolation
ABB SACE Emax 2 switch-disconnectors provide robust switching and isolation for modern low-voltage distribution systems. The E4.2V/MS platform combines a substantial 4000 A current rating with 100 kA short-time withstand capability, making it suitable for distribution assemblies exposed to high prospective fault currents.
The fixed construction and rear horizontal terminal arrangement enable straightforward integration into high-current switchboards and busbar systems. As an MS switch-disconnector configuration, the device is intended for switching and isolation, with suitable external protective equipment used where automatic overload and short-circuit protection is required.
Typical Applications
- High-current low-voltage main distribution switchboards.
- Industrial circuit switching and isolation.
- Manufacturing and process-industry power systems.
- Utility and infrastructure electrical distribution.
- Large commercial and institutional power systems.
- Switchboards using separately coordinated overcurrent protection.
