Why Choose the ABB MF383 Clamp Rail Expansion Module?
The ABB MF383, order code 2CPX041405R9999, is a mounted cable clamp rail expansion module designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides a dedicated solution for supporting and securing incoming and outgoing cables within commercial and industrial distribution cabinets.
The MF383 incorporates a cable clamp rail for strain relief of cables and conductors and is suitable for use with compatible bolt clamps. Its cable clamp rail is variably adjustable in depth using the deep angle piece, providing a usable depth range of 87–142 mm to accommodate different cable-routing and termination requirements.
With a module height of 1 GU / 150 mm, a panel width of 3 PW / 750 mm and 36 space units, the MF383 provides substantial cable-management capacity across a full three-panel-width section. It is suitable for cabinets from 200 mm depth and can be installed on compatible ABB EDF or WR mounting frames, which must be ordered separately.
Key Advantages
- Dedicated cable clamp rail expansion module for ABB CombiLine systems.
- Provides effective strain relief for cables and conductors entering or leaving the distribution cabinet.
- 3 PW / 750 mm panel width provides extensive space for organised cable management.
- Variably adjustable cable clamp rail provides a usable depth range of 87–142 mm.
- Compatible with ABB bolt clamps and saddle clamps for different cable diameters.
- Suitable for both EDF and WR mounting frames for flexible cabinet integration.

Reliable Cable Strain Relief and Management
Cable clamp rails provide mechanical strain relief for conductors entering or leaving an electrical distribution cabinet, helping prevent pulling forces from being transferred directly to terminals and connected equipment. The ABB MF383 provides a dedicated full-width rail arrangement for securing cables while maintaining an organised and serviceable cabinet layout.
The MF383 cable clamp rail can be adjusted in depth to provide a usable range of 87–142 mm, allowing the installation to be adapted to different cable sizes and routing requirements. Compatible ABB bolt clamps can be selected separately to suit the cable diameters used, making the module a flexible solution for professional CombiLine distribution assemblies.
Typical Applications
- Commercial and industrial sub-distribution boards.
- ABB CombiLine electrical cabinet assemblies.
- Incoming and outgoing cable strain relief.
- Power and control cable management.
- Industrial switchgear and distribution cabinets.
- Panel building and modular electrical distribution installations.
