Why Choose the ABB MBK214 Terminal Expansion 2PW?
The ABB MBK214 is an unassembled vertical terminal expansion module designed for ABB CombiLine N low-voltage subdistribution assemblies. Supplied under ABB order code 2CPX041844R9999 and forming part of the ABB DESUJ Sub Distribution product group, it provides a practical modular solution for installing terminal blocks and organising wiring within compatible electrical distribution cabinets.
The MBK214 features vertically arranged 35 × 15 mm DIN rails with a mounting arrangement that can be variably adjusted in depth using ABB deep angle pieces. This provides a usable installation depth of 66–113 mm, allowing the terminal mounting position to be adapted to different components and wiring requirements while maintaining an organised cabinet layout.
With a module height of 4 GU / 600 mm, width of 2 PW / 500 mm and capacity of 96 PLE, the MBK214 provides a usable terminal block height of 591 mm. It is suitable for grounded and insulated configurations and is designed for installation on compatible ABB EDF or WR mounting frames, with the mounting frame ordered separately.

Flexible Terminal Installation for Subdistribution Systems
Terminal expansion modules provide an organised mounting platform for terminal blocks and associated wiring within electrical distribution assemblies. The ABB MBK214 combines a 600 mm module height with a wider 500 mm format, providing 96 PLE of capacity for applications requiring substantial terminal and wiring space within a CombiLine N installation.
The vertically arranged DIN rails can be adjusted in depth to provide a usable range of 66–113 mm, helping installers accommodate different terminal block dimensions and wiring layouts. With 591 mm of usable terminal block height and compatibility with both EDF and WR mounting frames, the MBK214 supports flexible and orderly construction of professional low-voltage subdistribution systems.
Typical Applications
- Low-voltage electrical subdistribution boards.
- ABB CombiLine N distribution assemblies.
- High-capacity terminal block installations.
- Industrial and commercial electrical cabinets.
- Building services distribution panels.
- Modular switchgear and electrical control assemblies.
