Why Choose the ABB MBK113 Terminal Expansion 1PW?
The ABB MBK113 is an unmounted terminal expansion module designed for ABB low-voltage sub-distribution assemblies. Part of the ABB CombiLine N interior expansion system, it provides a structured mounting area for terminal blocks and associated wiring within professional electrical distribution panels.
The MBK113 uses vertically arranged 35 × 15 mm DIN rails that are variably adjustable in depth using the ABB ZW39P2 deep-angle piece. This configuration gives panel builders flexibility when positioning terminal blocks and routing conductors while supporting both grounded and insulated installation arrangements.
With a 3 GU / 450 mm height and 1 PW / 250 mm field width, the MBK113 provides 36 modular units of installation capacity. It offers a usable terminal-block height of 438 mm, a usable depth of 66–113 mm and is suitable for EDF and WR mounting frames in cabinets from 215 mm depth.

Flexible Terminal Mounting for Distribution Assemblies
Terminal expansion modules provide dedicated space for organising terminal blocks, conductors and field wiring within low-voltage electrical assemblies. The ABB MBK113 uses vertically arranged DIN rails to maximise usable terminal height while maintaining an organised and accessible wiring layout.
The adjustable DIN rail system allows the mounting depth to be adapted between 66 mm and 113 mm to suit different terminal blocks and wiring requirements. Combined with compatibility for EDF and WR mounting frames, the MBK113 provides a flexible solution for integrating terminal connections into ABB CombiLine N distribution systems.
Typical Applications
- ABB CombiLine N modular distribution assemblies.
- Low-voltage sub-distribution boards.
- Terminal block mounting and field wiring.
- Industrial and commercial electrical distribution panels.
- Switchgear and control-panel construction.
- Grounded or insulated terminal installations.
