Why Choose the ABB MT242 NH1 Fuse Switch Expansion 2PW?
The ABB MT242 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 2CPX041312R9999, the MT242 is a cabinet-mounted 2PW / two-field-width module prepared for the installation of two NH1 fuse switch disconnectors.
The MT242 has a module height of 3 RE / 450 mm, a field width of 2 FB / 500 mm and provides 72 space units. It is supplied unpopulated for two NH1 fuse switch disconnectors and is designed for a 3-pole busbar system with a maximum rated current of 440 A.
Designed for cabinets from 200 mm depth, the MT242 features plastic covers with equipment cut-outs, 90-degree press-and-turn fasteners and a RAL 7035 finish. The module can be expanded on compatible EDF or WR mounting frames, while the required mounting frame, NH1 fuse switch disconnectors and associated busbar accessories are selected separately.

Flexible Two-Way NH1 Fused Distribution
The ABB MT242 provides a dedicated CombiLine section for installing two NH1 fuse switch disconnectors within a 3-pole busbar system. Its unpopulated design allows compatible NH1 devices to be selected for the application, providing a structured platform for incorporating fuse protection and switch-disconnection functionality into outgoing low-voltage circuits.
With a 500 mm field width, 450 mm module height and 72 space units, the MT242 provides two NH1 positions while maintaining an organised cabinet layout. The module is supplied mounted for cabinet installation, while the fuse switch disconnectors, required busbar accessories and appropriate EDF or WR mounting frame are 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.
