Why Choose the ABB MK209 Terminal Expansion 2PW?
The ABB MK209 is a factory-assembled CombiLine terminal expansion module designed for mounting horizontal terminal blocks within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041237R9999, it provides a structured internal mounting solution for terminal connections and conductor organisation in sub-distribution assemblies.
The MK209 is configured for 2 panel widths (2 PW) with a field width of 500 mm and a module height of 600 mm. It provides 96 space units and uses horizontally arranged 35 × 15 mm DIN rails with perforations for wire holders, providing a practical platform for terminal block installation.
With a 150 mm row spacing, 438 mm usable terminal width and continuously adjustable mounting depth, the MK209 supports flexible panel construction and organised wiring. Its usable depth extends from 68–145 mm, while the module is suitable for compatible cabinets from 200 mm depth.

Reliable Terminal Expansion for Distribution Systems
Terminal expansion modules provide dedicated internal mounting space for terminal blocks used to terminate, distribute and organise electrical conductors within low-voltage distribution assemblies. The ABB MK209 combines horizontal DIN rail mounting with a generous usable width, helping panel builders create orderly terminal layouts while retaining convenient access for installation and servicing.
The continuously adjustable DIN rail depth allows the terminal mounting position to be adapted to different installation requirements, while the 150 mm row spacing provides practical room for conductor routing. As part of the ABB CombiLine system, the MK209 offers a coordinated solution for building organised and serviceable commercial and industrial distribution assemblies.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- Terminal block sections within electrical cabinets.
- Commercial building electrical distribution systems.
- Industrial power distribution panels.
- Control and automation cabinet terminal sections.
- Panel-building applications requiring organised terminal expansion.
