2CPX041294R9999 ABB MT236B NH00 Fuse Switch Expansion 2PW

Why Choose the ABB MT236B NH00 Fuse Switch Expansion 2PW?

The ABB MT236B is a factory-assembled CombiLine NH00 fuse switch-disconnector module designed for fused power distribution within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041294R9999, it is equipped with four ABB XLP NH00 fuse switch-disconnectors and an integrated three-pole busbar system.

The MT236B is configured for 2 panel widths (2 PW), with a field width of 500 mm and a module height of 300 mm. Its 2 RE format provides 48 space units, allowing four NH00 fuse switch-disconnectors to be integrated into a compact distribution field for commercial and industrial low-voltage assemblies.

The module incorporates a 3-pole busbar system rated up to 320 A with M8 connection screws and separator shutters for the fitted NH00 devices. The distance from the front edge of the equipment to the cover is 37 mm. Plastic covers with equipment cut-outs, a RAL 7035 finish and 90-degree press-and-turn closures complete the assembly, which is suitable for compatible cabinets from 200 mm depth.

Reliable NH00 Fuse Protection for Distribution Systems

NH fuse switch-disconnectors combine fuse-based circuit protection with switching and isolation functionality for low-voltage distribution circuits. The ABB MT236B integrates four NH00 fuse switch-disconnectors with a coordinated three-pole busbar system, providing an efficient way to create multiple fused outgoing circuits within a single CombiLine field.

With a maximum busbar-system current rating of 320 A, the MT236B provides a compact solution for commercial and industrial power distribution. Its factory-assembled design, separator shutters and coordinated protective covers simplify panel construction, while compatibility with EDF and WR mounting frames supports integration into a range of ABB distribution 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, switching and circuit isolation.
• Panel-building applications requiring four NH00 fuse switch-disconnectors in a 2 PW field.
