Why Choose the ABB MK114 Terminal Expansion 1PW?
The ABB MK114 is a vertical terminal block expansion module designed for structured terminal installation within ABB CombiLine electrical distribution systems. Supplied under ABB order code 2CPX041133R9999, this one-field-width module provides dedicated mounting space for terminal blocks in low-voltage distribution and switchgear cabinets.
The MK114 has a 4 RE / 600 mm module height and a 1 FB / 250 mm field width, providing 48 space units. It is equipped with a vertically arranged 35 × 15 mm DIN rail with perforations for wire holders, supporting an organised and accessible terminal installation.
Designed for cabinets from 200 mm depth, the MK114 provides a usable terminal-block height of 591 mm and an adjustable usable depth of 66–113 mm. The DIN-rail position can be continuously adjusted in depth, helping installers configure terminal mounting to suit the requirements of the distribution assembly.

Structured Terminal Expansion for Distribution Cabinets
Terminal expansion modules such as the ABB MK114 provide dedicated mounting space for terminal blocks inside electrical distribution assemblies. Its vertical DIN-rail arrangement helps panel builders organise terminal connections and wiring efficiently while maintaining an accessible and structured cabinet interior.
The MK114 is designed as part of the ABB CombiLine interior expansion system and combines a tall 600 mm module format with continuously adjustable mounting depth. It supports grounded and insulated configurations and can be installed using the appropriate EDF or WR mounting frame, which is ordered separately.
Typical Applications
- Low-voltage electrical distribution cabinets.
- ABB CombiLine interior expansion systems.
- Sub-distribution boards and switchgear assemblies.
- Vertical terminal block mounting and wiring organisation.
- Commercial and industrial electrical installations.
- Control and distribution cabinet interior expansion.
