Why Choose the ABB E6.2H/MS 4000 3p F HR Switch-Disconnector?
The ABB E6.2H/MS 4000 3p F HR, order code 1SDA073424R1, is a high-capacity 4000 A three-pole fixed switch-disconnector from the ABB SACE Emax 2 range, engineered for dependable switching and isolation in demanding low-voltage power distribution systems.
As an E6.2H/MS switch-disconnector, the device satisfies the isolation requirements associated with IEC 60947-3 and is intended for switching and isolation rather than automatic overcurrent protection. This makes it suitable for installations where coordinated protective devices elsewhere in the system provide overload and short-circuit protection.
The E6.2H/MS combines a rated uninterrupted current of 4000 A with a substantial rated short-time withstand current of 100 kA for 1 s and 3 s. Its fixed three-pole construction and rear horizontal terminals provide a robust solution for high-current industrial, infrastructure and main-distribution switchboards.
Key Advantages
- High-capacity 4000 A switch-disconnector for demanding low-voltage systems.
- Reliable switching and electrical isolation for high-current three-phase circuits.
- Three-pole configuration.
- Exceptional 100 kA short-time withstand current.
- Rated for operation up to 690 V AC.
- Fixed construction for permanent switchboard installation.
- Rear horizontal main-circuit terminals support high-current busbar connections.
- Robust E6.2 frame for critical power-distribution applications.
Key Features
- ABB SACE Emax 2 E6.2H/MS series.
- 4000 A rated uninterrupted current.
- Three-pole configuration.
- Switch-disconnector functionality without an integrated protection trip unit.
- 690 V AC rated operational voltage.

Heavy-Duty Switching and Isolation
ABB SACE Emax 2 switch-disconnectors provide robust high-current switching and isolation for modern low-voltage distribution systems. The E6.2H/MS platform combines a substantial 4000 A continuous-current rating with 100 kA short-time withstand capability, supporting installations with very high prospective fault currents.
The fixed construction and rear horizontal terminal arrangement enable integration into high-current switchboards and busbar systems. As an MS switch-disconnector configuration, the device provides switching and isolation while suitable coordinated protective equipment elsewhere in the installation provides automatic overload and short-circuit protection.
Typical Applications
- High-current low-voltage main distribution switchboards.
- Industrial circuit switching and isolation.
- Large manufacturing and process-industry power systems.
- Utility and infrastructure electrical distribution.
- Data centres and critical-power installations.
- Large commercial and institutional electrical systems.
