Why Choose the ABB MBT144 NH2 Fuse Switch Expansion 1PW?
The ABB MBT144 is a CombiLine N NH2 fuse switch-disconnector expansion module kit designed for fused power distribution within professional low-voltage electrical assemblies. Supplied under ABB order code 2CPX041782R9999, this 1PW module is prepared for the installation of one ABB NH2 fuse switch-disconnector.
The MBT144 is supplied unpopulated for an ABB ZH441 NH2 fuse switch-disconnector, which has a maximum rated current of 400 A. The module is intended for a three-pole busbar system and is supplied without separator shutters, allowing the appropriate switching, busbar and protective accessories to be selected for the completed distribution assembly.
The module has a height of 450 mm, a width of 250 mm and provides 36 space units in a compact single-field-width configuration. Installation is possible from a cabinet depth of 215 mm, and the MBT144 can be expanded on compatible EDF or WR mounting frames, which must be ordered separately.

Reliable NH2 Fused Power Distribution
NH fuse switch-disconnectors provide fuse-based overcurrent protection together with a defined means of circuit switching and isolation. The ABB MBT144 provides the modular interior arrangement required to integrate a single NH2 fuse switch-disconnector into a compatible CombiLine N distribution assembly.
When fitted with the appropriate ABB ZH441 device and compatible three-pole busbar arrangement, the MBT144 provides a structured solution for higher-current feeder circuits. Its single-field-width format is particularly useful where an NH2 fused outgoing or distribution circuit needs to be incorporated without occupying a larger multi-field module.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial switchboards.
- NH2 fused feeder circuits.
- Power distribution and circuit-isolation sections.
- Main and sub-distribution assemblies.
- Industrial electrical panel construction.
- ABB CombiLine N interior expansion systems.
