Why Choose the ABB MBR102 Busbar Module Expansion 1PW?
The ABB MBR102 is a modular busbar module expansion from the ABB CombiLine N interior expansion system. Supplied under ABB order code 2CPX041825R9999, this unpopulated module provides a dedicated horizontal 60 mm busbar section for compatible fuse switch disconnectors and bus-mounted fuse sockets within low-voltage sub-distribution assemblies.
Designed in a compact 1PW / one-field-width format, the MBR102 measures 250 mm wide × 300 mm high and provides 24 space units with a usable equipment width of 215 mm. It uses a 3-pole horizontal busbar system with a 60 mm busbar centre distance and supports up to three copper rails.
The MBR102 has a maximum rated current of 440 A and incorporates the ABB ZX146 busbar holder and ZX172 end cover. It is designed for vertical installation of compatible D0 and NH fuse switch disconnectors or bus-mounted fuse sockets, providing panel builders with a flexible platform for fused power distribution within professional ABB assemblies.

Flexible 60 mm Busbar Distribution for Fuse Equipment
The ABB MBR102 provides a structured 60 mm horizontal busbar system for the vertical installation of compatible fuse switch disconnectors and bus-mounted fuse sockets. Its three-pole arrangement supports up to three copper rails and provides a maximum rated current of 440 A, making the module suitable for compact but substantial power-distribution applications.
With a usable equipment width of 215 mm, the MBR102 can accommodate compatible D0 and NH fuse switch disconnectors or D02, E27 and E33 bus-mounted fuse equipment. The ZX146 busbar holder, 60 mm rail spacing and compatibility with EDF and WR mounting frames provide a coordinated ABB platform for organised and serviceable distribution-panel construction.
Typical Applications
- ABB CombiLine N sub-distribution assemblies.
- 3-pole 60 mm horizontal busbar systems.
- D0 and NH fuse switch disconnector installations.
- Bus-mounted fuse socket installations.
- Commercial and industrial low-voltage switchboards.
- Panel-building and distribution-board expansion projects.
