Why Choose the ABB MR102H Busbar Module Expansion 1PW?
The ABB MR102H, order code 2CPX041412R9999, is an unpopulated 60 mm vertical busbar expansion module designed for ABB CombiLine low-voltage sub-distribution systems. Supplied mounted and installed for cabinet integration, it provides a dedicated platform for the horizontal installation of compatible bus-mounted fuse sockets within a compact modular assembly.
The MR102H is designed for a 3-pole busbar system with up to three copper busbars and a maximum rated current of 250 A. It uses the ABB ZX146 busbar holder with a 60 mm busbar centre distance and provides 32 mm spacing between the copper busbar and protective cover. The busbars themselves must be selected and ordered separately.
The MR102H occupies 1 panel width (PW) and 2 grid units (GU), corresponding to 300 mm high × 250 mm wide with 24 space units (PLE). It provides a usable cut-out height of 134 mm, can be installed in cabinets from 120 mm deep and is compatible with EDF or WR mounting frames, which must be ordered separately.

Flexible Distribution with a 60 mm Vertical Busbar System
Vertical busbar modules provide a structured platform for distributing electrical power while allowing compatible protective and switching devices to be mounted directly onto the busbar system. The ABB MR102H uses a 3-pole 60 mm vertical busbar arrangement and is specifically configured for the horizontal installation of compatible bus-mounted fuse sockets.
With up to three copper busbars, a maximum rated current of 250 A and a usable cut-out height of 134 mm, the MR102H provides flexibility when configuring compact sub-distribution assemblies. Its 1-panel-width construction and minimum cabinet depth of only 120 mm make it particularly useful where installation space is limited.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial sub-distribution systems.
- ABB CombiLine cabinet assemblies.
- Horizontal installation of compatible bus-mounted fuse sockets.
- Three-pole 60 mm busbar distribution systems.
- Building services and electrical infrastructure distribution.
- Compact switchgear assemblies requiring modular fused outgoing circuits.
