Why Choose the ABB MBK109 Terminal Expansion 1PW?
The ABB MBK109 is a modular terminal expansion kit designed for horizontal terminal block installation 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.
The MBK109 uses horizontally arranged 35 × 15 mm DIN rails with perforations for wire holders. The rails can be continuously adjusted in depth using mounting brackets, providing flexible installation space for terminal blocks and associated wiring while maintaining an organised cabinet layout.
Configured for 1 panel width (1PW), the MBK109 measures 600 × 250 × 200 mm and provides 48 space units. It has a usable terminal width of 188 mm, a 150 mm row spacing and is suitable for cabinets from 200 mm depth, with a compatible EDF or WR mounting frame required separately.

Structured Terminal Installation for Distribution Systems
Terminal modules such as the ABB MBK109 provide dedicated mounting space for organising terminal blocks and associated wiring within low-voltage distribution cabinets. The horizontal DIN rail arrangement and adjustable mounting depth allow the terminal layout to be adapted 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. With its four-row, one-panel-width format, the MBK109 provides substantial terminal mounting capacity while retaining a compact cabinet footprint.
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.
