Why Choose the ABB MBK108K Terminal Expansion 1PW?
The ABB MBK108K is a CombiLine terminal expansion module designed for horizontally arranged terminal blocks in compatible ABB sub-distribution assemblies. Supplied as an unassembled kit under ABB order code 2CPX041636R9999, it provides a structured one-field-width solution for organising terminal connections within professional low-voltage distribution cabinets.
The MBK108K has a 1PW / one-field-width format measuring 250 mm wide and 450 mm high, corresponding to an installation height of 3 RE. It provides 36 PLE and uses horizontally arranged 35 × 7.5 mm DIN rails, with a 150 mm row spacing and 214 mm of usable width for terminal blocks.
Designed for compatible EDF or WR mounting frames, the MBK108K can be installed from a cabinet depth of 120 mm. Its closed plastic covers are finished in RAL 7035 and use 90-degree press-and-turn fasteners, helping create an orderly and protected terminal section within ABB CombiLine cabinet interiors.

Structured Terminal Installation in a Single Field Width
The ABB MBK108K provides a dedicated terminal section for modular sub-distribution assemblies, using horizontally arranged 35 × 7.5 mm DIN rails to support organised installation of compatible terminal blocks. With 214 mm of usable terminal width, 51 mm usable depth and 150 mm row spacing, the module provides practical installation space within a compact cabinet field.
Its 1PW format and compatibility with ABB EDF and WR mounting frames make the MBK108K suitable for integrating terminal functions into CombiLine cabinet interiors. The 3 RE / 450 mm height provides additional vertical installation space while retaining a narrow 250 mm field width for efficient cabinet planning.
Typical Applications
- ABB CombiLine modular sub-distribution assemblies.
- Horizontal terminal-block installation.
- Low-voltage electrical distribution cabinets.
- Commercial and industrial switchboards.
- Control and distribution panel terminal sections.
- Panel building, cabinet expansion and refurbishment projects.
