2CPX041842R9999 ABB MBK313 Terminal Expansion 3PW

Why Choose the ABB MBK313 Terminal Expansion 3PW?

The ABB MBK313 is a modular terminal expansion from the ABB CombiLine interior expansion system. Supplied under ABB order code 2CPX041842R9999, this unassembled interior fitting module is specifically designed for vertically arranged terminal blocks within compatible low-voltage sub-distribution assemblies.

Designed in a 3PW / three-field-width format, the MBK313 measures 750 mm wide × 450 mm high × 200 mm deep and provides 108 space units. It incorporates vertically arranged 35 × 15 mm DIN rails with perforations for wire holders, while the three-field-wide construction includes an additional stabilisation rail for increased mechanical support.

The DIN rails are continuously adjustable in depth using mounting brackets, providing a usable depth range of 66–113 mm and a usable terminal-block height of 438 mm. Closed RAL 7035 plastic covers and compatibility with both ABB EDF and WR mounting frames make the MBK313 a practical solution for structured terminal and wiring sections in professional distribution panels.

High-Capacity Vertical Terminal-Block Integration

The ABB MBK313 provides a dedicated three-field-wide terminal section for organising incoming, outgoing and internal panel wiring. Its vertically arranged 35 × 15 mm DIN rails provide a usable terminal-block height of 438 mm, while the additional stabilisation profile supports the wider rail arrangement for dependable terminal mounting.

Continuously adjustable mounting depth allows the DIN-rail position to be set between 66 mm and 113 mm to suit the selected terminal blocks and wiring arrangement. Compatibility with grounded and insulated installations and both EDF and WR mounting frames makes the MBK313 a flexible solution for large terminal sections within modular ABB distribution assemblies.

Typical Applications

• ABB CombiLine sub-distribution assemblies.
• High-capacity vertical terminal-block installations.
• Incoming and outgoing cable termination.
• Power and control wiring distribution.
• Commercial and industrial low-voltage switchboards.
• Panel-building and distribution-board expansion projects.
