Why Choose the ABB MK310 CombiLine Terminal Expansion Module?
The ABB MK310 is a CombiLine terminal expansion module designed for horizontal terminal block installation within compatible ABB low-voltage sub distribution assemblies. Identified by ABB order code 2CPX041241R9999, it is supplied assembled for cabinet installation and provides a large structured termination area for professional distribution systems.
The MK310 uses a 5-grid-unit, 3-panel-width format, corresponding to dimensions of 750 mm high × 750 mm wide × 200 mm deep. It provides 180 space units with a 150 mm row spacing and incorporates horizontal 35 × 15 mm omega-profile DIN rails for compatible terminal blocks.
With a generous 688 mm usable terminal width, the MK310 is suited to larger termination requirements. Its DIN rail arrangement can be continuously adjusted in depth, providing a usable depth range of 68 to 145 mm. Closed plastic covers finished in RAL 7035 complete the module, while a compatible ABB EDF or WR mounting frame is required separately.

High-Capacity Terminal Installation with ABB CombiLine
Terminal expansion modules provide an organised location for incoming, outgoing and internal conductor connections within electrical distribution assemblies. The ABB MK310 provides a substantial 688 mm usable terminal width and horizontal 35 × 15 mm omega-profile rails, making it particularly suitable for assemblies requiring extensive terminal block capacity.
The rail arrangement can be continuously adjusted to provide a usable depth between 68 and 145 mm, allowing the terminal position to be adapted to different wiring and installation requirements. Its standardised 5-grid-unit, 3-panel-width format enables the MK310 to be combined with other compatible CombiLine modules within an appropriate ABB mounting frame and enclosure.
Typical Applications
- Commercial low-voltage sub distribution assemblies.
- Industrial electrical distribution systems.
- High-capacity horizontal terminal block installations.
- Incoming and outgoing conductor termination.
- Building-services electrical distribution.
- Control and distribution panel wiring.
- ABB CombiLine assemblies requiring a large 3-panel-width terminal section.
