Why Choose the ABB MBK208 Terminal Expansion?
The ABB MBK208 is a CombiLine terminal expansion kit designed for horizontally arranged terminal blocks within ABB low-voltage sub-distribution assemblies. Supplied under ABB order code 2CPX041691R9999, it belongs to ABB’s DESUJ Sub Distribution product group and provides a structured internal installation solution for professional distribution boards and electrical cabinets.
The MBK208 is supplied as an unassembled internal installation module with horizontally arranged 35 × 15 mm perforated DIN rails. It provides three rows with 72 space units in total and a 150 mm row spacing. The DIN rails are continuously adjustable in depth using mounting brackets, providing flexibility when positioning terminal blocks and associated wiring.
With a module height of 450 mm, a 2PW field width of 500 mm and a usable terminal width of 438 mm, the MBK208 is designed for cabinets from 200 mm depth. The arrangement supports both earthed and insulated installations, while compatible ABB EDF or WR mounting frames are ordered separately.

Flexible Terminal Installation for Distribution Boards
Terminal expansion modules provide a structured mounting platform for terminal blocks used to organise incoming, outgoing and internal wiring within electrical distribution assemblies. Horizontal DIN rails enable terminals to be arranged clearly and securely while helping maintain an orderly wiring layout for installation and maintenance.
The ABB MBK208 provides three horizontally arranged DIN rails within a 2PW field, with 438 mm usable terminal width and continuously adjustable mounting depth. Its tiered rail arrangement and compatibility with ABB EDF or WR mounting frames make it suitable for professional CombiLine sub-distribution installations requiring flexible terminal mounting capacity.
Typical Applications
- Low-voltage sub-distribution boards.
- ABB CombiLine electrical distribution assemblies.
- Horizontal terminal block installations.
- Commercial and industrial distribution cabinets.
- Electrical panel building and cabinet expansion.
- Earthed and insulated terminal arrangements.
