Why Choose the ABB MT145 NH2 Fuse Switch Expansion 1PW?
The ABB MT145 is a CombiLine NH2 fuse switch-disconnector expansion module designed for integration into compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041326R9999, the module is mounted and installed in the cabinet and is supplied unpopulated for the installation of two NH2 fuse switch-disconnectors.
The MT145 is configured for 1 panel width (1 PW), with a field width of 250 mm and a module height of 750 mm. Its 5 RE format provides 60 space units, offering a compact vertical field for integrating two NH2 fused feeder positions into commercial and industrial distribution assemblies.
Designed for a 3-pole busbar system, the MT145 supports a maximum rated current of 630 A in the specified configuration. The module uses plastic covers with equipment cut-outs, a RAL 7035 finish and 90-degree press-and-turn closures. It is suitable for compatible cabinets from 215 mm depth and can be used with separately ordered EDF or WR mounting frames.

Flexible NH2 Fuse Protection for Distribution Systems
NH2 fuse switch-disconnectors combine high-capacity fuse protection with switching and isolation functionality for demanding low-voltage circuits. The ABB MT145 provides the prepared CombiLine infrastructure for installing two NH2 fuse switch-disconnectors, allowing panel builders to configure protected outgoing feeders within a narrow 1 PW cabinet field.
With a maximum rated current of 630 A and a three-pole busbar-system arrangement, the MT145 provides a coordinated platform for substantial commercial and industrial distribution applications. Its unpopulated format allows the required NH2 devices to be selected separately, while the factory-installed module and protective covers support efficient integration into compatible ABB distribution cabinets.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- NH2 fused outgoing feeder circuits.
- Commercial building power distribution.
- Industrial low-voltage distribution panels.
- Feeder protection, switching and circuit isolation.
- Panel-building applications requiring two NH2 fuse switch-disconnectors in a compact 1 PW field.
