Why Choose the ABB MBK114 Terminal Expansion 1PW?
The ABB MBK114 is an unassembled vertical terminal expansion module designed for ABB CombiLine N low-voltage subdistribution assemblies. Supplied under ABB order code 2CPX041843R9999 and forming part of the ABB DESUJ Sub Distribution product group, it provides a practical modular solution for installing terminal blocks within compatible distribution cabinets.
The MBK114 features a vertically arranged 35 × 15 mm DIN rail with perforations for wire holders. Its DIN rail position can be continuously adjusted in depth using deep mounting brackets, providing a usable installation depth of 66–113 mm and helping installers accommodate different terminal and wiring configurations within the enclosure.
With a module height of 4 GU / 600 mm, width of 1 PW / 250 mm and 48 PLE capacity, the MBK114 provides a usable terminal installation height of 591 mm. It is suitable for grounded and insulated configurations, can be used from a cabinet depth of 200 mm, and is designed for installation on compatible ABB EDF or WR mounting frames, which are 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 MBK114 uses a vertical DIN rail arrangement to maximise usable installation height while maintaining a compact single-field width, making it well suited to structured wiring and termination within CombiLine N cabinets.
The adjustable DIN rail depth allows the mounting position to be adapted between 66 mm and 113 mm to suit different terminal and wiring requirements. Combined with its 591 mm usable terminal height, closed protective cover and compatibility with EDF and WR mounting frames, the MBK114 supports flexible and orderly construction of professional low-voltage subdistribution assemblies.
Typical Applications
- Low-voltage electrical subdistribution boards.
- ABB CombiLine N distribution assemblies.
- Vertical terminal block installations.
- Industrial and commercial electrical cabinets.
- Building services distribution panels.
- Modular switchgear and electrical control assemblies.
