Why Choose the ABB MR103H Busbar Module?
The ABB MR103H is a purpose-designed busbar module for ABB CombiLine N subdistribution systems, providing a structured interior expansion solution for electrical distribution cabinets. Supplied under ABB order code 2CPX041413R9999, the MR103H is configured for a 1 PW module width and supports horizontal installation of bus-mounted fuse equipment on a vertical 60 mm busbar system.
As part of ABB's CombiLine N interior expansion system, the MR103H provides an organised and dependable platform for assembling distribution equipment around 3-pole busbars. The module incorporates ABB's ZX146 busbar bracket and provides 32 mm spacing between the copper rail and cover, supporting consistent installation within compatible ABB distribution enclosures.
The MR103H has a module height of 3 GU / 450 mm, a width of 1 PW / 250 mm and is designed for a maximum rated current of 250 A. Its 295 mm cut-out height provides 36 PLE of installation capacity, with use specified from a cabinet depth of 200 mm.

Reliable Busbar Integration for Subdistribution Systems
Busbar modules such as the ABB MR103H provide a controlled mechanical arrangement for positioning power-distribution components within modular switchboard and subdistribution assemblies. The 60 mm vertical busbar system allows compatible equipment to be installed in a consistent layout while maintaining defined spacing between live copper conductors and the front cover.
The MR103H is supplied unpopulated for horizontal installation of compatible bus-mounted fuse sockets and related equipment. Its CombiLine N format allows the module to form part of a structured ABB cabinet interior, although the required mounting frame must be selected separately and the module is not intended for fire-protection housing applications.
Typical Applications
- ABB CombiLine N subdistribution boards.
- Low-voltage electrical distribution cabinets.
- Busbar-based fuse distribution assemblies.
- Commercial and industrial power distribution systems.
- Modular switchboard interior expansion.
- Control and distribution panels requiring 3-pole busbar infrastructure.
