Why Choose the ABB MK108K Terminal Expansion Module?
The ABB MK108K is a 1PW terminal expansion module from the ABB CombiLine interior fitting system, designed for organised horizontal terminal-block installation in electrical sub-distribution assemblies. Supplied under ABB order code 2CPX041116R9999, it is an assembled interior fitting module for compatible ABB distribution systems.
The MK108K has a 1-field-width, 250 mm format with a height of 3 RE / 450 mm and provides 36 space units. Horizontally arranged 35 × 7.5 mm DIN rails provide a usable terminal-block width of 214 mm, with a fixed usable depth of 51 mm.
Designed for insulated construction, the DIN rails are fixed through insulating pieces and use a nominal row spacing of 150 mm. The MK108K is suitable for compatible EDF or WR mounting frames and can be used in cabinets from 120 mm depth, with the appropriate mounting frame ordered separately.

Organised Horizontal Terminal Block Installation
The ABB MK108K provides a dedicated mounting area for terminal blocks within compatible CombiLine electrical distribution assemblies. Its horizontally arranged 35 × 7.5 mm DIN rails, 214 mm usable terminal width and 150 mm row spacing support structured terminal layouts while keeping connection equipment organised and accessible.
With a 1PW format, 450 mm nominal height and 36 space units, the MK108K integrates with compatible EDF or WR mounting-frame systems. The required mounting frame is ordered separately, allowing the module to be incorporated into an appropriately configured ABB electrical sub-distribution enclosure.
Typical Applications
- Terminal-block expansion in ABB electrical sub-distribution boards.
- Horizontal terminal mounting in CombiLine assemblies.
- Commercial and industrial electrical distribution panels.
- Building-services electrical distribution systems.
- Control and distribution cabinets requiring organised terminal connections.
- Compatible EDF mounting-frame installations.
- Compatible WR mounting-frame installations.
- Insulated interior fitting arrangements requiring a 1PW terminal module.
