Why Choose the ABB MK313 Terminal Expansion 3PW?
The ABB MK313 is a vertical terminal block expansion module for ABB CombiLine interior distribution systems, designed to provide organised mounting space for terminal blocks within electrical distribution and switchgear cabinets. Supplied under ABB order code 2CPX041132R9999, the MK313 is a three-field-width configuration intended for structured terminal expansion in professional low-voltage installations.
The MK313 provides 3 raster units (RE), equivalent to 450 mm in height, together with a 3-field-width (FB) configuration of 750 mm. It offers 108 space units and uses vertically arranged 35 × 15 mm DIN rails, providing a practical mounting platform for terminal blocks while maintaining an orderly cabinet layout.
Designed for cabinets from 200 mm depth, the module provides a usable terminal-block height of 438 mm and an adjustable usable depth from 66–113 mm. The DIN-rail assembly can be continuously adjusted in depth using deep-angle pieces, while the three-field-wide rail arrangement incorporates additional stabilisation for dependable mechanical support.

Structured Terminal Expansion for Distribution Cabinets
Terminal expansion modules such as the ABB MK313 provide dedicated mounting space for terminal blocks inside electrical distribution assemblies. The vertical DIN-rail arrangement helps installers organise wiring and terminal connections efficiently while maintaining a structured and serviceable cabinet interior.
As part of the ABB CombiLine interior expansion system, the MK313 combines a large three-field-width format with adjustable mounting depth and a stabilised DIN-rail arrangement. It can be used with EDF or WR mounting frames, which are ordered separately, and supports both grounded and insulated installation arrangements.
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.
