Why Choose the ABB E2.2N/MS 800 3p F HR Switch-Disconnector?
The ABB E2.2N/MS 800 3p F HR, order code 1SDA073402R1, is an 800 A three-pole fixed switch-disconnector from the ABB SACE Emax 2 range, designed for dependable switching and isolation in low-voltage power distribution systems.
As an E2.2N/MS switch-disconnector, the device is intended for circuit switching and isolation rather than automatic overcurrent protection. It is therefore well suited to installations where fault and overload protection is provided by separate protective equipment while a robust high-current isolation device is required.
The E2.2N/MS combines an 800 A rated uninterrupted current with a rated short-time withstand current of 66 kA for 1 s. Its three-pole fixed construction and rear horizontal terminals provide a practical configuration for integration into industrial and commercial low-voltage switchboards.
Key Advantages
- High-capacity 800 A switch-disconnector for low-voltage power distribution.
- Reliable switching and isolation for three-phase electrical systems.
- Three-pole configuration.
- Robust 66 kA short-time withstand current for 1 s.
- 690 V AC rated operational voltage.
- Fixed construction for permanent switchboard installations.
