Why Choose the ABB MBK106K Terminal Expansion 1PW?
The ABB MBK106K is an unassembled terminal expansion kit designed for ABB ComfortLine Compact CU and CombiLine N sub-distribution systems. Supplied under ABB order code 2CPX041632R9999, it provides a structured mounting arrangement for terminal blocks within modular electrical distribution assemblies.
This terminal expansion uses horizontally arranged 35 × 7.5 mm DIN rails fixed by insulating pieces, providing an organised platform for terminal block installation. The design supports insulated mounting and is intended for use with the appropriate ABB mounting frame, which is ordered separately.
The MBK106K provides a module height of 1 GU / 150 mm and a width of 1 PW / 250 mm, corresponding to 12 modular units. The usable terminal-block width for a one-field-width configuration is 214 mm, with DIN rails arranged at 150 mm spacing.

Structured Terminal Distribution for Electrical Assemblies
Terminal expansion modules such as the ABB MBK106K provide an organised DIN-rail platform for terminal blocks used to distribute and terminate conductors inside electrical distribution assemblies. The modular arrangement helps simplify wiring, identification and maintenance while maintaining a consistent internal panel layout.
The ComfortLine Compact CU and CombiLine N system uses standardised field widths and grid dimensions to support configurable distribution-board construction. The MBK106K integrates into this modular system and requires the appropriate mounting frame for installation within the enclosure.
Typical Applications
- ABB ComfortLine Compact CU distribution boards.
- CombiLine N modular distribution assemblies.
- Terminal block mounting and conductor termination.
- Commercial and industrial sub-distribution boards.
- Electrical control and distribution cabinets.
- Modular panel-building and switchboard applications.
