Why Choose the ABB MBF283 Clamp Rail Expansion 2PW?
The ABB MBF283, order code 2CPX041823R9999, 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 MBF283 is supplied as a kit for installation within compatible ABB mounting systems and incorporates a cable clamp rail suitable for bolt clamps. Its design supports secure cable routing while helping reduce mechanical strain on cable terminations, making it suitable for professional switchboard, panel building and electrical distribution applications.
With a width of 2 PW / 500 mm, a height of 1 GU / 150 mm and compatibility with cabinets from 200 mm depth, the MBF283 provides 24 PLE of installation width. 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 cables and provide mechanical strain relief before conductors reach terminals, devices and distribution components. This helps create a more orderly installation while reducing unwanted mechanical loading on electrical connections.
The ABB MBF283 forms part of the CombiLine N modular interior expansion system and is designed for integration into compatible ABB sub-distribution cabinets. Its adjustable cable clamp rail allows installers to position cable support according to the available 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.
