Why Choose the ABB MK108 Terminal Expansion 1PW?
The ABB MK108, order code 2CPX041233R9999, is a CombiLine terminal block module designed for horizontal terminal arrangements within professional electrical sub-distribution systems. Its 1PW / 1-field configuration combines a compact 250 mm field width with three rack units of terminal mounting space.
The MK108 has a nominal module height of 3 RE / 450 mm and provides 36 space units. It incorporates 35 × 15 mm perforated top-hat rails for terminal blocks, with a 150 mm row spacing and a usable terminal width of 188 mm.
Designed for flexible panel construction, the terminal rails can be continuously adjusted in depth using deep-mounting brackets, providing a usable depth range of 68–145 mm. Closed plastic covers, a 90-degree press-and-turn closure and an RAL 7035 finish complete the assembly, which is suitable from a cabinet depth of 200 mm and requires a compatible EDF or WR mounting frame ordered separately.

Flexible Horizontal Terminal Expansion for Distribution Systems
Terminal block modules provide structured mounting space for connecting and distributing conductors within electrical distribution assemblies. The ABB MK108 combines a 35 × 15 mm top-hat rail system, 150 mm row spacing and 188 mm usable terminal width to support organised horizontal terminal arrangements within a compact single-field section.
The continuously adjustable 68–145 mm usable depth allows the terminal rail position to be adapted to installation requirements. With its 3 RE / 450 mm height and 1PW format, the MK108 provides a practical terminal expansion solution for compatible CombiLine assemblies using EDF or WR mounting frames.
Typical Applications
- Electrical sub-distribution systems.
- Horizontal terminal block arrangements.
- ABB CombiLine interior expansion systems.
- EDF and WR mounting-frame assemblies.
- Commercial building distribution boards.
- Industrial electrical panels.
- Structured conductor termination and distribution.
- Distribution-board expansion and refurbishment projects.
