Why Choose the ABB MBK314 Terminal Expansion 3PW?
The ABB MBK314, order code 2CPX041845R9999, is a terminal block expansion kit designed for ABB CombiLine N interior expansion systems used in sub-distribution boards and electrical distribution enclosures. As part of the ABB DESUJ Sub Distribution product group, it provides a dedicated installation field for terminal blocks within professional low-voltage distribution assemblies.
The MBK314 incorporates vertically arranged 35 × 15 mm DIN rails for mounting terminal blocks and associated components. The DIN rails can be variably adjusted in depth using the ABB ZW39P2 deep angle piece, allowing the terminal field to be configured for different installation requirements while supporting both grounded and insulated setups.
With a width of 3 PW / 750 mm and a height of 4 GU / 600 mm, the MBK314 provides a large terminal installation area for demanding distribution applications. It is designed for cabinets from 215 mm depth and provides a usable terminal block height of 591 mm with an adjustable usable depth of 66–113 mm.
Key Advantages
- Purpose-designed terminal block expansion for ABB CombiLine N systems.
- Large 3 PW / 750 mm installation width for extensive terminal arrangements.

Flexible Terminal Installation for Distribution Systems
Terminal expansion fields provide dedicated mounting space for terminal blocks used to organise and distribute electrical connections within switchboards and sub-distribution assemblies. The vertically arranged DIN rails of the ABB MBK314 provide a structured mounting platform while allowing installers to organise extensive groups of terminals within a clearly defined installation field.
The ABB MBK314 forms part of the CombiLine N modular interior expansion system and is designed for professional panel building and electrical distribution applications. Its adjustable DIN rail depth, large 3 PW width and 591 mm usable terminal block height make it particularly suitable for distribution assemblies requiring substantial terminal capacity and flexible component positioning.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine N cabinet systems.
- Terminal block mounting and connection fields.
- Commercial and industrial electrical distribution panels.
- Switchboard and control panel construction.
- Grounded and insulated terminal arrangements.
- EDF and WR mounting frame expansion assemblies.
