Why Choose the ABB MBK310 Terminal Expansion 3PW?
The ABB MBK310 is a terminal expansion module kit designed for structured terminal-block installation within ABB CombiLine electrical distribution assemblies. Supplied under ABB order code 2CPX041705R9999, this 3PW module provides a spacious internal expansion solution for professional low-voltage distribution boards, switchboards and electrical panel-building applications.
The MBK310 is designed for horizontal terminal-block mounting using 35 × 15 mm DIN rails. Its three-field-width configuration provides substantial usable terminal space, while an additional stabilising rail supports the DIN-rail arrangement across the wider module. The mounting depth can be continuously adjusted using depth-mounting brackets, helping panel builders accommodate different terminal and wiring requirements.
With a module height of 750 mm, field width of 750 mm and overall depth of 200 mm, the MBK310 provides 180 space units and approximately 688 mm usable terminal width. It is supplied as an unassembled kit and is intended for use with a compatible ABB EDF or WR mounting frame, which is ordered separately.

Reliable Terminal Organisation for Distribution Assemblies
Terminal expansion modules such as the ABB MBK310 provide dedicated installation space for terminal blocks within professional electrical distribution assemblies. The horizontal DIN-rail layout supports clear separation and organisation of terminal connections, helping panel builders create accessible wiring arrangements for incoming, outgoing and internal conductors.
The MBK310 combines a wide three-field format with adjustable installation depth and an additional stabilising rail, making it particularly suitable for distribution assemblies requiring substantial terminal capacity. Its modular CombiLine construction enables the terminal section to be integrated consistently with other compatible ABB interior expansion modules.
Typical Applications
- Low-voltage electrical distribution boards.
- Large terminal-block sections in modular switchboards.
- Commercial and industrial distribution assemblies.
- Electrical panel building and system integration.
- Incoming and outgoing circuit termination.
- Control and power distribution panels.
- ABB CombiLine interior expansion systems.
