Why Choose the ABB MK109 Terminal Expansion?
The ABB MK109 is a factory-assembled CombiLine terminal expansion module designed for horizontal terminal-block installation within compatible ABB sub-distribution cabinets. Supplied under ABB order code 2CPX041236R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a 1 PW / 250 mm field width.
The MK109 has a 4 RE / 600 mm nominal height and provides 48 space units. It uses 35 × 15 mm top-hat DIN rails for horizontally arranged terminal blocks, with a 150 mm row spacing and a usable terminal-block width of 188 mm.
For flexible terminal positioning, the DIN-rail arrangement is continuously adjustable in depth using depth-mounting brackets, providing a usable depth range of 68–145 mm. The module has closed RAL 7035 plastic covers with 90-degree press-and-turn fasteners and is suitable for cabinets from 200 mm deep; the compatible EDF or WR mounting frame is ordered separately.
