NH2 Double Shutter Integration in Electrical Distribution Systems
Low-voltage electrical distribution systems use equipment-specific accessories to achieve their intended mechanical arrangement and support the integration of electrical components. NH fuse equipment is available in different designated sizes, making correct accessory selection important when constructing or modifying a distribution board. The ABB ZH449 is identified as an NH2 double shutter, providing a dedicated accessory option for compatible distribution equipment requiring this particular configuration.
The double shutter designation distinguishes the ZH449 from single shutter accessories and helps installers identify the appropriate component for their intended assembly. Selection should be based on the relevant ABB distribution system documentation, including the associated equipment arrangement and mounting requirements. The ZH449 is a shutter accessory rather than a complete fuse switch or protective device, and the electrical ratings, accessibility and protection level of the finished assembly depend on the installed equipment and enclosure system.
Typical Applications
- Compatible ABB low-voltage electrical distribution assemblies.
- NH2 equipment arrangements requiring a double shutter accessory.
- Electrical sub-distribution panel construction.
