Why Choose the ABB MR202B Busbar Module Expansion?
The ABB MR202B is a populated busbar module expansion for ABB sub-distribution assemblies, supplied under ABB order code 2CPX041410R9999. Designed as part of the ABB CombiLine N interior expansion system, the module provides a structured solution for integrating vertically installed three-pole bus-mounted fuse equipment into electrical distribution cabinets.
The MR202B is configured for the CombiLine N horizontal 60 mm busbar system and is designed for equipment with vertically installed three-pole bus-mounted fuse sockets. Its populated construction supports efficient panel assembly while maintaining the modular arrangement required for professional low-voltage distribution systems.
With a module height of 300 mm, width of 500 mm and a minimum cabinet depth of 200 mm, the MR202B provides 48 PLE of installation capacity. The populated module is intended for bus-mounted fuse socket applications with a rated current of up to 250 A.
