Why Choose the ABB MBF383 Clamp Rail Expansion 3PW?
The ABB MBF383, order code 2CPX041824R9999, is a cable clamp rail expansion kit designed for ABB CombiLine N interior expansion systems used in sub-distribution boards and electrical distribution enclosures. As part of ABB’s DESUJ Sub Distribution product group, it provides organised cable support and effective strain relief for cables and conductors within compatible cabinet assemblies.
The MBF383 is supplied as an unassembled interior expansion kit incorporating a cable clamp rail suitable for bolt clamps. It is designed to support secure cable routing and reduce mechanical strain on cable terminations, while its closed plastic cover provides a neat finish within professional switchboard and distribution panel installations.
With a width of 3 PW / 750 mm, a height of 1 GU / 150 mm and suitability for cabinets from 200 mm depth, the MBF383 provides 36 PLE of installation capacity. The cable clamp rail can be variably adjusted in depth using the ABB ZW59P2 deep angle piece, providing a usable depth range of 87–142 mm.

Reliable Cable Management for Distribution Assemblies
Cable clamp rails are used within electrical distribution assemblies to support incoming and outgoing cables and provide mechanical strain relief before conductors reach terminals, devices and distribution components. This helps create an organised installation while reducing unwanted mechanical loading on electrical connections.
The ABB MBF383 forms part of the CombiLine N modular interior expansion system and is designed for integration into compatible ABB sub-distribution cabinets. Its wide 3 PW format provides cable management across a 750 mm field, while the adjustable cable clamp rail allows installers to position cable support according to cabinet depth and routing requirements.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine N cabinet systems.
- Commercial and industrial electrical distribution panels.
- Switchboard and control panel construction.
- Cable support and strain relief within electrical enclosures.
- EDF and WR mounting frame expansion assemblies.
