Why Choose the ABB MBT345 NH2 Fuse Switch Expansion 3PW?
The ABB MBT345 is a modular NH2 fuse switch disconnector expansion kit designed for ABB CombiLine electrical distribution systems. Supplied under ABB order code 2CPX041787R9999, this unassembled interior fitting module provides a dedicated solution for installing up to six NH2 fuse switch disconnectors within compatible low-voltage sub-distribution assemblies.
The MBT345 is designed for use with a 3-pole busbar system and is supplied unequipped, allowing the required NH2 fuse switch disconnectors to be selected separately. Compatible ABB ZH441 NH2 fuse switch disconnectors are rated up to 400 A, while the MBT345 module supports a maximum busbar system rated current of 630 A.
With a 5 GU / 750 mm height and 3 PW / 750 mm field width, the MBT345 provides 180 space units. Its plastic covers feature equipment cut-outs and 90-degree press-and-turn closures, while the module is suitable for installation from a cabinet depth of 225 mm using a separately ordered WR mounting frame.

High-Capacity NH2 Fuse Switch Distribution
NH2 fuse switch disconnectors combine fuse protection with switching and isolation functionality for higher-current outgoing circuits in low-voltage electrical distribution systems. The ABB MBT345 provides the modular infrastructure required to integrate up to six compatible NH2 fuse switch disconnectors into a structured CombiLine distribution assembly.
The 3 PW format provides substantial equipment capacity, while the 3-pole busbar arrangement supports a maximum rated current of 630 A. This makes the MBT345 particularly suitable for commercial and industrial distribution boards requiring multiple high-current fused outgoing circuits in an organised modular installation.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine distribution assemblies.
- NH2 fused outgoing circuits.
- High-current low-voltage power distribution.
- Commercial and industrial electrical installations.
- Switchgear and distribution panel construction.
