Why Choose the ABB MT336B NH00 Fuse Switch Expansion 3PW?
The ABB MT336B is a CombiLine NH00 fuse switch disconnector expansion module designed for structured low-voltage power distribution within professional electrical cabinets. Supplied under ABB order code 2CPX041295R9999, the MT336B is a fully populated, cabinet-mounted module in a 3PW / 750 mm-wide configuration.
The module is equipped with six ABB NH00 fuse switch disconnectors and incorporates a 3-pole, 320 A busbar system. With a module height of 2 RE / 300 mm, a width of 3 PW / 750 mm and 72 space units, the MT336B provides a practical integrated solution for multiple fused outgoing circuits.
Designed for cabinets with a minimum depth of 200 mm, the MT336B features plastic covers with equipment cut-outs, RAL 7035 finish and 90-degree press-and-turn fasteners. Its pre-equipped construction simplifies the integration of NH00 fused switching into compatible ABB CombiLine distribution assemblies, while the required EDF or WR mounting frame is ordered separately.

Integrated NH00 Fused Distribution
The ABB MT336B combines six NH00 fuse switch disconnectors with a common 3-pole busbar system to provide an integrated fused distribution section within a CombiLine cabinet. This arrangement enables multiple outgoing circuits to be organised within a single module while providing fuse protection and switch-disconnection functionality for each NH00 position.
With its 750 mm width, 72 space units and maximum rated current of 320 A, the MT336B is suited to substantial low-voltage distribution applications requiring multiple NH00 fused ways. The module 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.
- Multi-circuit fused power distribution sections.
- Professional panel-building and electrical installation projects.
