Why Choose the ABB MK113 Terminal Expansion Module?
The ABB MK113 is a purpose-designed CombiLine terminal expansion module for vertical terminal blocks, providing structured terminal mounting within compatible ABB sub-distribution enclosures. Supplied under ABB order code 2CPX041130R9999, it forms part of the ABB DESUJ Sub Distribution product range and is configured as a 1 PW field-width module.
The MK113 is equipped with a vertically arranged 35 × 15 mm DIN rail with perforations for wire holders. The DIN rail is continuously adjustable in depth through its mounting bracket, providing a usable terminal depth of approximately 66–113 mm and a usable terminal-block height of 438 mm.
Configured with a 250 mm field width and 450 mm module height, the MK113 provides 36 space units and is suitable for cabinets from 200 mm deep. Its modular construction makes it a practical solution for organised terminal installation in ABB electrical distribution systems.

Organised Vertical Terminal Expansion for Distribution Systems
Terminal expansion modules provide dedicated mounting space for terminal blocks used to connect incoming, outgoing and internal conductors within electrical distribution systems. A vertical DIN-rail arrangement makes effective use of enclosure height while maintaining accessible, structured wiring for installation and maintenance.
The ABB MK113 is engineered for the CombiLine interior expansion system and combines a compact 250 mm field width with 36 space units and 438 mm of usable terminal-block height. Its depth-adjustable mounting arrangement provides additional flexibility when configuring terminal blocks and associated wiring within compatible ABB cabinets.
Typical Applications
- Electrical sub-distribution boards.
- Vertical terminal-block installations within ABB CombiLine systems.
- Commercial building electrical distribution.
- Industrial electrical control and distribution panels.
- Incoming and outgoing conductor termination.
- Structured terminal and wiring installations in compatible ABB enclosures.
