Why Choose the ABB AG174 2 × NH2 Cover 250 × 750 mm 1PW?
The ABB AG174 is a purpose-designed NH2 fuse equipment cover for electrical distribution assemblies, intended for a configuration of two NH size 2 fuse equipment positions within compatible low-voltage distribution panels. As part of ABB's DESUJ Sub Distribution product range, this cover supports the construction, organisation and maintenance of electrical distribution systems incorporating NH fuse equipment.
The AG174 features a 2 × NH2 cover configuration, providing a dedicated panel covering arrangement for two NH2 equipment positions. Its design helps electrical panel builders organise fuse equipment within compatible distribution assemblies while maintaining a neat and consistent front-facing installation. The cover is an assembly accessory rather than a fuse holder, fuse-switch disconnector or electrical protective device.
With nominal dimensions of 250 mm wide × 750 mm high and a 1PW panel-width configuration, the ABB AG174 is intended for compatible ABB sub-distribution arrangements requiring two NH2 equipment positions. Identified by ABB order code 2CPX062900R9999, it provides a practical solution for electrical distribution board construction, equipment integration, replacement and refurbishment projects.

Reliable Integration for NH2 Fuse Distribution Assemblies
NH fuse systems are widely used in low-voltage electrical distribution installations where appropriately rated fuse links and associated equipment provide overcurrent protection and, where suitable switching devices are installed, circuit isolation. NH size 2 identifies a standardised fuse-link size used with compatible fuse bases and fuse-switch disconnectors. Purpose-designed equipment covers help provide an organised front-facing arrangement around these components.
The ABB AG174 is specifically identified for a two-position NH2 configuration, with nominal dimensions of 250 mm × 750 mm and a 1PW panel-width designation. These characteristics allow electrical panel builders to identify the corresponding cover for compatible ABB sub-distribution arrangements incorporating NH2 fuse equipment.
Correct selection of the cover and associated fuse equipment is essential for a safe and functional installation. The AG174 itself does not provide overcurrent protection or electrical isolation; these functions depend on separately installed protective and switching devices. The completed assembly's degree of protection, electrical clearances, accessibility and operational safety depend on the complete enclosure design, equipment compatibility and correct installation.
