Why Choose the ABB MBR202 Busbar Module Expansion 2PW?
The ABB MBR202 is a modular busbar module expansion from the ABB CombiLine N interior expansion system. Supplied under ABB order code 2CPX041826R9999, it provides a dedicated horizontal 60 mm busbar section for integrating compatible fuse switch disconnectors and bus-mounted fuse sockets into low-voltage sub-distribution assemblies.
Designed in a 2PW / two-field-width format, the MBR202 measures 500 mm wide × 300 mm high, provides 48 space units and offers a usable equipment width of 465 mm. The module uses a 3-pole horizontal busbar system with a 60 mm busbar centre distance and supports a maximum of three copper busbars.
The MBR202 is rated up to 440 A and incorporates the ABB ZX146 busbar holder and ZX172 end cover. It is designed for vertical installation of compatible D0 and NH00 fuse switch disconnectors or bus-mounted fuse sockets, providing a flexible platform for organised fuse-based power distribution in professional ABB assemblies.
Key Advantages
- Purpose-designed 60 mm horizontal busbar module for ABB CombiLine N assemblies.

Flexible 60 mm Busbar Distribution for Fuse Equipment
The ABB MBR202 provides a structured 60 mm horizontal busbar system for vertically installed fuse equipment. Its three-pole configuration supports up to three copper rails and a maximum rated current of 440 A, creating a coordinated platform for distributing power to compatible fuse switch disconnectors and bus-mounted fuse sockets.
With a usable equipment width of 465 mm, the MBR202 provides considerably more installation space than a single-field module while retaining the same 300 mm module height. Compatibility with D0 and NH00 fuse switch disconnectors, D02, E27 and E33 bus-mounted fuse sockets, and EDF or WR mounting frames makes it suitable for flexible professional distribution-board construction.
Typical Applications
- ABB CombiLine N sub-distribution assemblies.
- 3-pole 60 mm horizontal busbar systems.
- D0 and NH00 fuse switch disconnector installations.
- Bus-mounted fuse socket installations.
- Commercial and industrial low-voltage switchboards.
- Panel-building and distribution-board expansion projects.
