Why Choose the ABB ZH448 NH2 Single Shutter?
The ABB ZH448 (2CPX062965R9999) is a purpose-designed NH2 single separator shutter for compatible low-voltage electrical distribution assemblies. Developed for the ABB CombiLine N interior expansion system, this component is used with NH2 fuse switch disconnector modules to provide a correctly matched shutter arrangement and support protection against accidental contact with hazardous electrical parts.
As part of ABB's DESUJ Sub Distribution product group, the ZH448 is designed for three-field-width NH2 fuse switch disconnector modules. Its single-shutter configuration is suitable for compatible M(B)T344 and M(B)T345 module arrangements, helping electrical panel builders achieve consistent equipment integration and maintain the intended protective construction of the distribution assembly.
Manufactured from plastic with a colour similar to RAL 7035 light grey, the ABB ZH448 has listed dimensions of 287 mm × 246 mm × 305 mm (height × width × depth). The shutter is specified to support IPXXC protection against access to hazardous parts when correctly installed in the appropriate assembly, making it an important accessory for professional electrical distribution installations.

Reliable Contact Protection for NH2 Fuse Switch Disconnector Assemblies
NH fuse switch disconnector systems are widely used in low-voltage power distribution installations where fuse-based circuit protection and disconnection are required. Correctly selected separator shutters form part of the protective construction of these assemblies, helping prevent unintended access to hazardous electrical parts and supporting the required level of contact protection.
The ABB ZH448 NH2 Single Shutter is specifically intended for compatible CombiLine N M(B)T344 and M(B)T345 modules. According to ABB's module arrangement, one ZH448 shutter is used for a fully assembled M(B)T344 module, while two are used for a fully assembled M(B)T345 module. The component's design supports IPXXC contact protection as part of the correctly configured electrical distribution assembly.
Unlike an NH fuse switch disconnector, the ZH448 is a protective separator shutter rather than a current-carrying switching device. It does not provide fuse protection or circuit isolation independently. Installation should be carried out by qualified electrical personnel in accordance with ABB's assembly instructions and the requirements of the complete distribution system.
Typical Applications
- ABB CombiLine N electrical sub-distribution assemblies.
- NH2 fuse switch disconnector modules.
- Three-field-width M(B)T344 and M(B)T345 module installations.
- Commercial low-voltage electrical distribution panels.
- Industrial switchgear and power distribution cabinets.
- Electrical distribution assemblies requiring IPXXC contact protection.
- Professional electrical panel-building and switchgear construction.
- Replacement of compatible NH2 separator shutters during maintenance and refurbishment.
