Why Choose the ABB MT136B NH00 Fuse Switch Expansion 1PW?
The ABB MT136B is a factory-assembled CombiLine NH00 fuse switch-disconnector module designed for protected power distribution within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041293R9999, the module is pre-equipped with two ABB XLP NH00 fuse switch-disconnectors and a coordinated three-pole busbar system.
The MT136B is configured for 1 panel width (1 PW), with a field width of 250 mm and a module height of 300 mm. Its 2 RE format provides 24 space units, creating a compact solution for integrating two NH00 fuse switch-disconnectors into commercial and industrial sub-distribution assemblies.
The integrated 3-pole busbar system has a maximum rated current of 320 A and uses M8 connection screws. Plastic covers with equipment cut-outs, a RAL 7035 finish and 90-degree press-and-turn closures complete the module. The MT136B is suitable for compatible cabinets from 200 mm depth, with the required EDF or WR mounting frame ordered separately.

Reliable NH00 Fuse Protection for Distribution Systems
NH fuse switch-disconnectors combine fuse-based circuit protection with a means of safely switching and isolating electrical circuits. The ABB MT136B integrates two NH00 fuse switch-disconnectors with a coordinated three-pole busbar system, providing a compact way to incorporate fused outgoing circuits into CombiLine low-voltage distribution assemblies.
With a maximum module current rating of 320 A, the MT136B is suited to applications requiring robust fused distribution within a relatively narrow cabinet field. Its factory-assembled design, separator shutters and coordinated protective covers support efficient panel construction while the EDF and WR mounting options allow integration into a range of compatible ABB cabinet configurations.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- NH00 fused outgoing circuits.
- Commercial building power distribution.
- Industrial low-voltage distribution panels.
- Feeder protection and circuit isolation.
- Panel-building applications requiring two NH00 fuse switch-disconnectors in a compact 1 PW field.
