Why Choose the ABB MT342 NH1 Fuse Switch Expansion Module?
The ABB MT342 is an NH1 fuse switch expansion module designed for ABB CombiLine N sub-distribution assemblies, providing an unpopulated modular solution for integrating NH1 fuse switch disconnectors into low-voltage distribution systems. Supplied under ABB order code 2CPX041313R9999, it forms part of the DESUJ Sub Distribution product range.
This expansion module is intended for use with ABB NH1 fuse switch disconnectors such as the ZH431 and is configured for a 3-pole busbar system. Its modular construction supports structured switchgear assembly while allowing the appropriate fuse switch disconnector to be selected and installed separately.
The MT342 provides capacity for three NH1 fuse switch disconnectors across a 750 mm module width. It is suitable for expansion on WR mounting frames and is designed for cabinets with a minimum depth of 225 mm.

Modular Fuse Switch Distribution for CombiLine N Systems
NH fuse switch modules are used in low-voltage distribution assemblies to provide organised accommodation for fused switching and circuit isolation. The ABB MT342 provides the mechanical and busbar-system arrangement needed to integrate multiple NH1 fuse switch disconnectors within a CombiLine N installation.
Its modular layout makes it suitable for building or extending structured sub-distribution boards where dependable protection, isolation and maintainable equipment organisation are required.
Typical Applications
- Commercial and industrial low-voltage distribution boards.
- ABB CombiLine N switchgear assemblies.
- NH fuse switch disconnector installations.
- Sub-distribution panels and power distribution cabinets.
- Industrial electrical switchboards.
- Expansion of modular fuse-protected outgoing circuits.
