Why Choose the ABB ZX129 Insulating Plate?
The ABB ZX129 (2CPX039129R9999) is a dedicated insulating plate for NH2 fuse switch-disconnector busbar systems, designed to insulate unoccupied busbar ends within compatible ABB electrical distribution assemblies. Part of the ABB DESUJ Sub Distribution product group, it provides a system-specific solution for completing unused positions in professional low-voltage distribution installations.
The ZX129 is specifically intended for unoccupied busbar ends associated with NH2 fuse switch-disconnectors. It is suitable for compatible ABB M(B)T144 to M(B)T345 modules, providing an insulating barrier where busbar ends would otherwise remain unused within the assembly.
Measuring 200 mm wide × 110 mm high × 30 mm deep, the ZX129 is supplied as a complete accessory with the required fastening material included. Its dedicated NH2 compatibility makes it a straightforward choice for panel builders constructing or modifying compatible ABB CombiLine N and 185 mm busbar-system assemblies.

Dedicated Insulation for Unoccupied NH2 Busbar Ends
Unused positions within busbar-based fuse switch-disconnector assemblies require suitable system components to maintain a correctly configured installation. The ABB ZX129 is specifically designed for unoccupied busbar ends associated with NH2 fuse switch-disconnectors, providing a dedicated insulating plate for compatible ABB distribution modules.
The ZX129's 200 × 110 × 30 mm format is engineered for its defined busbar-system application rather than use as a general-purpose insulating sheet. Supplied with fastening material and compatible with M(B)T144 through M(B)T345 modules, it provides panel builders with a practical ABB system accessory for completing NH2 distribution assemblies containing unused busbar positions.
Typical Applications
- NH2 fuse switch-disconnector assemblies.
- Insulation of unoccupied busbar ends.
- ABB CombiLine N distribution systems.
- Compatible ABB 185 mm busbar systems.
- Electrical sub-distribution boards.
- Low-voltage busbar distribution systems.
- Commercial and industrial electrical distribution cabinets.
- Switchboard and panel-building applications.
