Why Choose the ABB MBU357 Meter Plate Expansion 3PW?
The ABB MBU357 is a CombiLine measuring device expansion module designed for integrating panel-mounted electrical measuring instruments into compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041810R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a dedicated, factory-prepared field for switchboard metering and monitoring equipment.
Designed for a 3-panel-width (3PW) configuration, the MBU357 has a nominal size of 150 mm high × 750 mm wide and provides 36 space units. The module is supplied unequipped and is prepared for the installation of 4 measuring instruments with 96 × 96 mm installation dimensions, arranged horizontally across the field.
The MBU357 is supplied as an unassembled kit with plastic covers incorporating the required instrument cut-outs and mounting on a cross beam. The covers are finished in RAL 7035 and secured using 90-degree press-and-turn fasteners. It is suitable for cabinets from 225 mm depth and can be installed using compatible ABB EDF or WR mounting frames, which must be ordered separately.

Wide-Format Mounting for Four 96 × 96 mm Measuring Instruments
The ABB MBU357 provides a dedicated 750 mm-wide metering field for four measuring instruments with 96 × 96 mm installation dimensions. Its horizontal arrangement allows multiple electrical measurements to be presented together in a clear switchboard interface, making the module suitable for compatible ammeters, voltmeters, multifunction meters and other panel-mounted measuring devices.
Because the MBU357 is supplied unequipped, the measuring instruments can be selected according to the monitoring requirements of the distribution system. The prepared cut-out covers and mounting cross beam simplify integration into compatible ABB cabinet assemblies, while the 3PW format provides additional horizontal space compared with narrower CombiLine measuring device modules.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- Panel-mounted electrical metering and monitoring.
- Multifunction power meter installations.
- Commercial and industrial sub-distribution boards.
- Switchboard voltage, current, power and energy monitoring.
- Professional panel-building and system integration projects.
