Why Choose the ABB MU357 Measuring Device Expansion?
The ABB MU357 is a dedicated measuring device expansion module designed for ABB CombiLine N sub-distribution systems. Supplied under ABB order code 2CPX041391R9999, this 3-panel-width assembly provides a structured mounting solution for incorporating electrical measuring instruments into compatible distribution cabinets.
The MU357 is supplied unpopulated and prepared for the installation of up to four measuring devices with 96 × 96 mm installation dimensions. The measuring devices are arranged horizontally, while covers with prepared cut-outs provide an organised and professional front-facing installation within the distribution assembly.
With a height of 150 mm, width of 750 mm and 36 PLE capacity, the MU357 is designed for cabinets from 225 mm depth. It mounts on a mounting cross beam and can be used with compatible ABB EDF or WR mounting frames, which must be ordered separately.

Structured Measurement Integration for Distribution Systems
Electrical measuring devices provide operators with important information about the condition and performance of low-voltage distribution systems. Dedicated measuring-device modules allow meters and monitoring instruments to be incorporated into switchboards in an organised format while maintaining accessibility and a consistent panel layout.
The ABB MU357 provides four horizontally arranged 96 × 96 mm instrument positions within a 3-panel-width CombiLine N module. Its prepared covers and mounting-cross-beam installation simplify the integration of compatible measuring devices into ABB sub-distribution cabinets while retaining the modular construction of the overall system.
Typical Applications
- Commercial and industrial sub-distribution boards.
- Low-voltage electrical distribution cabinets.
- Panel-mounted electrical measuring instruments.
- Energy and electrical parameter monitoring installations.
- ABB CombiLine N modular distribution systems.
- Industrial switchboard and electrical panel-building projects.
