Why Choose the ABB MK214 Terminal Expansion Module?
The ABB MK214 is a factory-assembled vertical terminal block expansion module designed for the ABB CombiLine internal mounting system used in low-voltage distribution cabinets. Supplied under ABB order code 2CPX041134R9999, it provides a structured mounting area for terminal blocks where substantial terminal capacity and organised conductor routing are required.
The MK214 is configured for 2 panel widths (2 PW), corresponding to a field width of 500 mm, and has a module height of 600 mm. It provides 96 space units and incorporates vertically arranged 35 × 15 mm DIN rails with perforations for wire holders, providing a practical platform for terminal installation and wiring management.
The DIN rails can be continuously adjusted in depth using the compatible deep-angle mounting arrangement, providing a usable depth range of 66–113 mm. With a usable terminal mounting height of 591 mm and suitability for cabinets from 200 mm depth, the MK214 offers a flexible terminal expansion solution for ABB sub-distribution assemblies.

Reliable Terminal Expansion for Distribution Systems
Terminal expansion modules provide dedicated mounting space for the terminal blocks used to terminate, distribute and organise electrical conductors within low-voltage distribution assemblies. The ABB MK214 combines vertically arranged DIN rails with a substantial usable mounting height, helping panel builders create structured terminal layouts and maintain accessible wiring.
The adjustable DIN rail depth allows the terminal mounting position to be adapted to installation requirements, while the CombiLine modular format supports coordinated integration with other ABB internal mounting components. This makes the MK214 particularly suitable for distribution cabinets requiring extensive terminal capacity within a standardised modular layout.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine distribution assemblies.
- Terminal block expansion within electrical cabinets.
- Commercial building distribution systems.
- Industrial electrical distribution panels.
- Control and automation cabinet terminal sections.
