Why Choose the ABB MR102 Busbar Module Expansion?
The ABB MR102, order code 2CPX041406R9999, is a mounted 60 mm busbar module expansion designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides a compact 3-pole busbar platform for integrating fuse switching and fuse-holder equipment into commercial and industrial sub-distribution cabinets.
The MR102 is supplied unequipped for the vertical installation of compatible D0 and NH fuse switch disconnectors or bus-mounted fuse sockets, including equipment sizes D02, E27 and E33. Its horizontal 60 mm busbar system uses ABB ZX146 busbar holders and accommodates up to three copper rails, allowing the final protective equipment configuration to be selected for the application.
With a module height of 2 GU / 300 mm, a panel width of 1 PW / 250 mm, 24 space units and a usable width of 215 mm, the MR102 provides a compact busbar distribution solution. The system is rated up to 440 A and is suitable for expansion on compatible ABB EDF or WR mounting frames, with the mounting frame and copper busbars ordered separately.

Flexible 60 mm Busbar Power Distribution
A 60 mm busbar system provides a compact platform for distributing electrical power to compatible bus-mounted protective and switching devices. The ABB MR102 combines a 3-pole horizontal busbar arrangement with vertical equipment mounting, allowing compatible fuse switch disconnectors and fuse sockets to be integrated into a structured CombiLine distribution assembly.
The MR102 is supplied unequipped so that the appropriate D0 or NH fuse switch disconnector or bus-mounted fuse socket can be selected according to the installation requirements. Its ZX146 holders accommodate up to three copper busbars with 60 mm centre spacing, while the system’s maximum rated current of 440 A makes it suitable for substantial commercial and industrial sub-distribution applications.
Typical Applications
- Commercial and industrial sub-distribution boards.
- ABB CombiLine electrical cabinet assemblies.
- 60 mm busbar distribution systems.
- D0 and NH fused distribution circuits.
- Bus-mounted fuse socket installations.
- Industrial switchgear and modular power distribution systems.
