Why Choose the ABB MBT237 NH00 Fuse Switch Expansion 2PW?
The ABB MBT237 is a modular NH00 fuse switch disconnector expansion kit designed for ABB CombiLine N electrical distribution systems. Supplied under ABB order code 2CPX041774R9999, this unassembled interior fitting module provides a dedicated mounting solution for up to eight NH00 fuse switch disconnectors within compatible sub-distribution enclosures.
The MBT237 is designed for a 3-pole busbar system and is supplied unequipped, allowing suitable NH00 fuse switch disconnectors to be selected separately for the application. Its modular design enables efficient integration of fused outgoing circuits into professional low-voltage distribution assemblies while maintaining an organised and accessible panel layout.
With a 4 GU / 600 mm height and 2 PW / 500 mm field width, the MBT237 provides 96 space units and supports a maximum rated current of 320 A. The module incorporates plastic covers with equipment cut-outs and is suitable for installation in cabinets with a minimum depth of 200 mm.

Reliable NH00 Fuse Switch Distribution
NH00 fuse switch disconnectors combine fuse protection, switching and isolation functionality for outgoing circuits in low-voltage electrical distribution systems. The ABB MBT237 provides the modular infrastructure required to integrate up to eight compatible NH00 fuse switch disconnectors into a structured CombiLine N distribution assembly.
The MBT237's 2 PW format offers twice the device capacity of a comparable 1 PW module while retaining the same 600 mm module height. Its 3-pole busbar configuration and maximum 320 A rated current make it a practical solution for installations requiring multiple fused outgoing circuits within a compact and organised distribution panel.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine N distribution assemblies.
- NH00 fused outgoing circuits.
- Low-voltage power distribution systems.
- Commercial and industrial electrical installations.
- Switchgear and distribution panel construction.
