Why Choose the ABB E1.2N/MS 800 3p F F Switch-Disconnector?
The ABB E1.2N/MS 800 3p F F, order code 1SDA073395R1, is a SACE Emax 2 fixed air switch-disconnector designed for reliable isolation and switching in low-voltage electrical distribution systems. Part of the ABB Emax 2 E1.2 family, this three-pole device has a rated uninterrupted current of 800 A and uses the E1.2N/MS switch-disconnector configuration.
Unlike an Emax 2 circuit breaker equipped with an electronic protection trip unit, the E1.2N/MS is a switch-disconnector intended primarily for switching and isolation duties. It provides a clear solution for applications where circuit protection is provided elsewhere in the installation and a robust high-current switching and isolation device is required.
This version is supplied in a fixed three-pole configuration with front terminals. It supports operating voltages up to 690 V AC and provides a rated short-time withstand current of 50 kA, making it suitable for demanding industrial and commercial distribution assemblies.
Key Advantages
- 800 A rated uninterrupted current for high-current low-voltage distribution systems.
- E1.2N/MS switch-disconnector configuration for dependable switching and circuit isolation.
- Three-pole construction for three-phase electrical distribution applications.
- Fixed installation provides a compact and permanent switchboard solution.
- Front terminals support practical main-circuit connection within switchgear assemblies.
- 50 kA short-time withstand current provides robust performance under high prospective fault-current conditions.
- Suitable for operation at voltages up to 690 V AC.

Reliable High-Current Switching and Isolation
The ABB Emax 2 E1.2N/MS is designed to provide controlled switching and isolation of high-current low-voltage circuits. As a switch-disconnector, it enables sections of an electrical installation to be disconnected from the supply for operational control, maintenance and servicing while integrating into the established Emax 2 switchgear platform.
With an 800 A current rating, 50 kA short-time withstand capability and operation up to 690 V AC, the E1.2N/MS 800 is suited to substantial industrial and commercial distribution systems. Its fixed construction and front-terminal arrangement provide a straightforward solution for switchboards where withdrawable functionality is not required.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power-distribution systems.
- High-current circuit switching and isolation.
- Transformer secondary distribution assemblies.
- Commercial and infrastructure electrical installations.
- Switchgear systems where upstream or downstream devices provide circuit protection.
