Why Choose the ABB MT137 NH00 Fuse Switch Expansion Module?
The ABB MT137, order code 2CPX041302R9999, is a mounted NH00 fuse switch disconnector expansion module designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides a structured solution for integrating multiple NH00 fuse switch disconnectors into commercial and industrial sub-distribution cabinets.
The MT137 is supplied unequipped for the installation of up to four NH00 fuse switch disconnectors rated up to 160 A, including compatible ABB ZH411 and ZH412 devices. It is designed for a 3-pole 320 A busbar system, allowing panel builders to create compact fused distribution arrangements while selecting the appropriate fuse switch disconnectors separately for the application.
With a module height of 4 RE / 600 mm, a panel width of 1 FB / 250 mm and 48 space units, the MT137 provides substantial vertical capacity in a compact single-panel-width format. The module is suitable for both EDF and WR mounting frames and requires a cabinet depth of at least 200 mm, with the compatible mounting frame ordered separately.

Reliable NH00 Fused Power Distribution
NH00 fuse switch disconnectors combine switching, isolation and fuse protection functions within electrical distribution systems. The ABB MT137 provides the modular infrastructure required to integrate up to four compatible NH00 fuse switch disconnectors into a CombiLine assembly, supporting organised fused outgoing circuits and straightforward access for installation and maintenance.
The MT137 is supplied unequipped so that compatible ABB ZH411 or ZH412 NH00 fuse switch disconnectors can be selected according to the requirements of the installation. Its 3-pole 320 A busbar system and compact 250 mm panel width make it particularly suitable where several fused outgoing circuits are required within a relatively narrow distribution cabinet section.
Typical Applications
- Commercial and industrial sub-distribution boards.
- ABB CombiLine electrical cabinet assemblies.
- NH00 fused outgoing circuits.
- Industrial power distribution systems.
- Electrical switchgear and control cabinets.
- Panel building and modular distribution installations.
