Why Choose the ABB MBK106 Terminal Expansion 1PW?
The ABB MBK106 is a modular terminal expansion kit designed for horizontal terminal block installations within ABB low-voltage sub-distribution assemblies. Part of the ABB CombiLine system and DESUJ Sub Distribution range, it provides a structured internal mounting solution for terminal blocks in compatible electrical cabinets and distribution boards.
Designed as an unassembled internal installation module, the MBK106 incorporates a horizontally arranged 35 × 15 mm DIN rail with perforations for wire holders. The rail is continuously adjustable in depth using mounting brackets, providing a usable terminal depth of 68–115 mm and a usable terminal width of 188 mm.
The MBK106 is configured for 1 panel width (1PW), with a nominal module size of 150 × 250 × 200 mm. It provides 12 space units with a 150 mm row spacing and is suitable for cabinets from 200 mm depth, with the compatible EDF or WR mounting frame ordered separately.

Structured Terminal Installation for Distribution Systems
Terminal modules such as the ABB MBK106 provide a dedicated mounting area for organising electrical terminal blocks and associated wiring within low-voltage distribution cabinets. The horizontal DIN rail and continuously adjustable mounting depth allow the terminal arrangement to be adapted to the installation while maintaining accessibility for connection, inspection and maintenance.
The ABB CombiLine modular system allows panel builders to combine compatible internal installation modules according to the required cabinet layout. The MBK106 provides a compact one-panel-width terminal mounting solution for grounded or insulated installations and integrates with compatible EDF or WR mounting structures.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB CombiLine cabinet systems.
- Terminal block mounting and expansion.
- Commercial and industrial electrical panels.
- Control and power distribution cabinets.
- Structured field wiring and termination assemblies.
