Why Choose the ABB MT142 NH1 Fuse Switch Expansion 1PW?
The ABB MT142 is a CombiLine NH1 fuse switch disconnector expansion module designed for structured fused power distribution within low-voltage electrical cabinets. Supplied under ABB order code 2CPX041311R9999, the MT142 is a cabinet-mounted 1PW / single-field-width module prepared for the installation of one ABB NH1 fuse switch disconnector.
The MT142 has a module height of 3 RE / 450 mm, a field width of 1 FB / 250 mm and provides 36 space units. It is supplied unpopulated for one NH1 fuse switch disconnector and is designed for use with the ABB ZH431, rated up to 250 A, within a 3-pole busbar system.
The module supports a maximum rated current of 440 A in its single-level busbar arrangement and is suitable for cabinets from 200 mm depth. Plastic covers with equipment cut-outs, 90-degree press-and-turn fasteners and a RAL 7035 finish complete the assembly, while the required EDF or WR mounting frame is ordered separately.

Flexible NH1 Fused Distribution
The ABB MT142 provides a dedicated CombiLine section for installing one NH1 fuse switch disconnector within a 3-pole busbar arrangement. Its unpopulated design allows the compatible ABB ZH431 fuse switch disconnector to be selected and installed as required, providing fuse protection and switch-disconnection functionality for an outgoing low-voltage circuit.
With a compact 250 mm field width, 450 mm module height and 36 space units, the MT142 provides an efficient way to incorporate NH1 fused distribution into compatible ABB cabinet assemblies. The module is supplied mounted in the cabinet configuration, while the NH1 fuse switch disconnector and appropriate EDF or WR mounting frame must be selected separately.
Typical Applications
- Low-voltage power distribution cabinets.
- ABB CombiLine sub-distribution assemblies.
- NH1 fused outgoing circuit distribution.
- Commercial and industrial switchgear assemblies.
- Fuse-protected feeder and distribution circuits.
- Professional panel-building and electrical installation projects.
