Why Choose the ABB E2.2H/MS 1000 3p FHR Switch-Disconnector?
The ABB E2.2H/MS 1000 3p FHR, order code 1SDA073405R1, is a high-performance three-pole switch-disconnector from the ABB SACE Emax 2 range, designed for switching and isolation duties in low-voltage power distribution systems. With a rated uninterrupted current of 1000 A, it combines the E2.2 frame with the H/MS performance level for demanding industrial and infrastructure applications.
Unlike an Emax 2 circuit breaker equipped with an electronic protection release, the E2.2H/MS is a switch-disconnector configuration intended primarily for switching and isolation. This makes it suitable for installations where circuit protection is provided by other devices within the electrical system while a robust, high-current disconnection point is required.
This version is supplied in a fixed three-pole configuration with rear horizontal terminals. It is rated for operation up to 690 V AC and provides a rated short-time withstand current of 85 kA, making it suitable for high-fault-level low-voltage switchboards and power distribution assemblies.
Key Advantages
- High-current 1000 A three-pole switch-disconnector for low-voltage power distribution.
- Part of the proven ABB SACE Emax 2 E2.2 platform.
- 85 kA short-time withstand capability for demanding electrical networks.
- Rated for operation up to 690 V AC.
- Fixed construction provides a robust solution for permanent switchboard installations.
- Rear horizontal terminals support practical integration into compatible distribution assemblies.

High-Current Switching and Isolation for Power Distribution
Switch-disconnectors provide controlled switching and electrical isolation within low-voltage distribution systems. In an Emax 2 MS configuration, the device provides the switching and isolation functions of the Emax 2 platform without the electronic overcurrent protection release normally associated with an air circuit breaker, allowing protection to be coordinated through other devices in the installation.
The E2.2H/MS 1000 combines a 1000 A continuous current rating with an 85 kA short-time withstand capability and operation up to 690 V AC. Its fixed construction and rear horizontal terminals make it well suited to main switchboards and other high-current distribution assemblies requiring a dependable three-pole isolation point.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- High-current switching and isolation applications.
- Commercial and infrastructure electrical installations.
- Transformer and generator distribution systems.
- Switchgear assemblies where overcurrent protection is provided by separate protective devices.
- Incoming and outgoing distribution circuits requiring a fixed isolation device.
