Why Choose the ABB MT137B NH00 Fuse Switch Expansion 1PW?
The ABB MT137B is a CombiLine NH00 fuse switch disconnector expansion module designed for structured fused power distribution within low-voltage electrical cabinets. Supplied under ABB order code 2CPX041296R9999, the MT137B is a cabinet-mounted 1PW / single-panel-width module equipped with four NH00 fuse switch disconnectors.
The MT137B has a module height of 4 RE / 600 mm, a panel width of 1 PW / 250 mm and provides 48 space units. Its four ABB NH00 fuse switch disconnectors are integrated with a 3-pole busbar system, providing a compact solution for multiple fused outgoing circuits within a single CombiLine section.
With a maximum rated current of 320 A, the MT137B is suitable for substantial low-voltage distribution duties while retaining a compact 250 mm cabinet width. Plastic covers with equipment cut-outs, 90-degree press-and-turn fasteners and a RAL 7035 finish complete the module, which is designed for cabinets from 200 mm depth.

Compact NH00 Fused Distribution
The ABB MT137B combines four NH00 fuse switch disconnectors with a common 3-pole busbar system to create a compact fused distribution section within a single 250 mm panel width. Each NH00 position provides fuse protection together with switch-disconnection functionality, making the module suitable for organising multiple outgoing circuits within professional low-voltage assemblies.
The 600 mm-high arrangement provides four NH00 switching positions and 48 space units while the integrated busbar system supports a maximum rated current of 320 A. The MT137B is supplied mounted for cabinet installation, while the appropriate EDF or WR mounting frame must be selected and ordered separately.
Typical Applications
- Low-voltage power distribution cabinets.
- ABB CombiLine sub-distribution assemblies.
- NH00 fused outgoing circuit distribution.
- Commercial and industrial switchgear assemblies.
- Compact multi-circuit fused power distribution sections.
- Professional panel-building and electrical installation projects.
