Why Choose the ABB MBK112 Terminal Expansion 1PW?
The ABB MBK112 is an unassembled vertical terminal expansion module designed for ABB CombiLine distribution assemblies. Supplied under ABB order code 2CPX041837R9999, it provides a dedicated DIN rail mounting platform for terminal blocks within compatible low-voltage distribution boards and cabinets.
The MBK112 incorporates a 35 × 15 mm vertical DIN rail with perforations for wire holders. The complete DIN rail assembly can be continuously adjusted in depth using deep-mounting brackets, providing a usable installation depth of 66–113 mm and a usable terminal mounting height of 244 mm.
With a height of 300 mm, width of 250 mm and cabinet-depth requirement of at least 200 mm, the MBK112 corresponds to a 2 RE × 1 PW configuration and provides 24 space units. Closed RAL 7035 plastic covers with 90-degree press-and-turn closures complete the module, while the required EDF or WR mounting frame is ordered separately.

Structured Terminal Distribution for Electrical Assemblies
Terminal expansion modules provide dedicated mounting space for terminal blocks used to organise incoming, outgoing and internal wiring within low-voltage electrical assemblies. The vertical DIN rail arrangement of the ABB MBK112 makes efficient use of a narrow 1 PW field while providing a structured platform for conductor termination and distribution.
As part of the ABB CombiLine system, the MBK112 can be integrated into compatible modular cabinet interiors using EDF or WR mounting frames. Its 244 mm usable terminal height and continuously adjustable 66–113 mm installation depth allow the terminal rail position to be adapted to the requirements of the installed terminal blocks and wiring arrangement.
Typical Applications
- ABB CombiLine modular distribution assemblies.
- Vertical terminal-block installations.
- Incoming and outgoing conductor termination.
- Commercial and industrial sub-distribution boards.
- Electrical control and distribution cabinets.
- Panel-building and switchboard applications.
