Why Choose the ABB MK107K Terminal Expansion Module?
The ABB MK107K is a purpose-designed CombiLine terminal expansion module for horizontal installation of terminal blocks within compatible ABB sub-distribution enclosures. Supplied under ABB order code 2CPX041114R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides an organised interior mounting solution for professional electrical distribution installations.
The MK107K is equipped with a horizontally arranged 35 × 7.5 mm DIN rail for terminal blocks, with a fixed mounting arrangement and a 150 mm row spacing. It provides a usable terminal-block width of 214 mm and a usable depth of 51 mm, helping installers create structured and accessible wiring layouts.
Configured as a 1 PW / 250 mm wide module with a height of 2 RE / 300 mm, the MK107K provides 24 space units and can be used from a cabinet depth of 120 mm. It features a closed plastic cover in RAL 7035 with a 90-degree push-turn fastener and is designed for use with compatible EDF or WR mounting frames.

Organised Terminal Expansion for Distribution Systems
Terminal expansion modules provide structured mounting space for terminal blocks used to connect incoming, outgoing and internal conductors within electrical distribution systems. Horizontal DIN-rail mounting helps create clear wiring arrangements, improves accessibility and supports efficient installation and maintenance.
The ABB MK107K is engineered for the CombiLine interior expansion system and combines a compact 250 mm field width with 24 space units and 214 mm of usable terminal-block width. Its modular construction makes it well suited to professional distribution-board assemblies where organised terminal capacity and compatibility with ABB enclosure systems are required.
Typical Applications
- Electrical sub-distribution boards.
- Terminal-block expansion within ABB CombiLine systems.
- Commercial building electrical distribution.
- Industrial electrical control and distribution panels.
- Incoming and outgoing conductor termination.
- Structured terminal and wiring installations in compatible ABB enclosures.
