2CPX041404R9999 ABB MF283 Clamp Rail Expansion 2PW

Why Choose the ABB MF283 Clamp Rail Expansion 2PW?

The ABB MF283, order code 2CPX041404R9999, is a mounted CombiLine cable clamp rail expansion module designed for structured cable management within ABB electrical sub-distribution systems. Part of the ABB CombiLine interior expansion system and the DESUJ Sub Distribution product group, it provides a dedicated cable strain-relief area for cables and conductors entering or passing through a distribution cabinet.

The MF283 has a 1 RE / 150 mm height and a two-panel-width configuration of 500 mm, providing 24 space units. It includes a cable clamp rail for bolt clamps, creating an organised mounting point for securing incoming and outgoing cables and helping prevent mechanical loads from being transferred directly to terminals and electrical equipment.

The cable clamp rail is variably adjustable in depth using the ABB ZW59P2 deep-angle piece, providing a usable depth range from 87 mm to 142 mm. The MF283 uses closed plastic covers with 90-degree press-and-turn closures and a RAL 7035 light-grey finish, and it can be installed on ABB EDF or WR mounting frames in cabinets from 200 mm depth.

Structured Cable Strain Relief and Management

Effective strain relief helps prevent pulling forces and other mechanical loads on incoming and outgoing cables from being transferred directly to electrical terminals, devices and connection points. The ABB MF283 provides a dedicated cable clamp rail within the CombiLine system, allowing cables and conductors to be secured in an organised position before they are routed to their electrical connections.

With a variable usable depth of 87 mm to 142 mm and a 500 mm two-panel-width configuration, the MF283 provides additional cable-management capacity for larger distribution assemblies. Its adjustable rail, closed cover and compatibility with EDF and WR mounting frames make it a practical solution for professional commercial and industrial cabinet installations.

Typical Applications

• Commercial and industrial sub-distribution boards.
• Cable strain relief in electrical distribution cabinets.
• Incoming and outgoing cable management.
• Electrical switchboards and distribution assemblies.
• Structured conductor routing and mechanical support.
• Building-services electrical distribution systems.
• ABB CombiLine cabinet expansion and interior fit-out.
