Why Choose the ABB E2.2N/MS 1000 3p F HR Switch-Disconnector?
The ABB E2.2N/MS 1000 3p F HR, order code 1SDA073404R1, is a robust three-pole fixed air switch-disconnector from the ABB SACE Emax 2 range. Rated at 1000 A, it is designed for dependable switching and isolation duties in demanding low-voltage electrical distribution systems where high current capability and reliable circuit separation are required.
The E2.2N/MS configuration is a switch-disconnector rather than an automatic circuit breaker fitted with an electronic protection release. It provides a rated short-time withstand current of 66 kA for 1 s, allowing it to withstand substantial prospective fault currents while coordinated upstream or downstream protective devices perform automatic fault interruption.
This version combines a fixed three-pole construction with rear horizontal (HR) terminals for integration into low-voltage switchboards. Its 690 V AC maximum rated operational voltage, compact E2.2 frame and proven Emax 2 architecture make it suitable for industrial, commercial and infrastructure distribution systems requiring reliable high-current switching and isolation.

Reliable High-Current Switching and Isolation
The ABB Emax 2 E2.2N/MS is designed for electrical installations requiring high-current switching and dependable circuit isolation without integrated automatic overcurrent protection. Its combination of a 1000 A continuous current rating, 690 V AC operational capability and 66 kA short-time withstand rating for 1 s makes it suitable for coordinated power distribution systems where separate protective devices provide fault protection.
The fixed three-pole construction and rear horizontal terminals make the 1SDA073404R1 particularly suitable for integration into low-voltage switchboards and distribution assemblies. Its Emax 2 architecture provides robust switching performance in a compact format, while optional motorised operation and voltage-release accessories provide additional flexibility for switchboard control requirements.
Typical Applications
- Main and secondary isolation in low-voltage switchboards.
- Industrial power distribution systems.
- Bus-section and bus-coupler switching applications.
- Commercial and infrastructure electrical distribution.
- Manufacturing plants and process facilities.
- Data centres and critical power distribution systems.
- Utility and energy distribution installations.
- Switchboards using separate upstream or downstream overcurrent protection.
- High-current systems requiring 66 kA short-time withstand capability.
- Applications requiring fixed rear-horizontal switchboard connections.
