ABB M4M network analyzers monitor electrical parameters, energy consumption and power quality in distribution systems. The range includes DIN-rail M4M 2X and front-panel M4M 20, M4M 30 and M4M 32. Compare the mounting format, measurement requirements and communication version before using the model and order-code references below for an enquiry.

M4M 2X: DIN-Rail Monitoring
DIN-rail installation without a local display, with remote access via the selected communication protocol and Bluetooth. PQ1, PQ2 and RTS packages provide different analysis and recording functions; specify the complete version.
M4M 20: Electrical Monitoring
Front-panel analyzer with a colour graphic display and pushbuttons. Provides electrical-parameter and energy monitoring with basic power-quality measurements such as THD.
M4M 30: Power Quality & Recording
Front-panel analyzer with a colour touchscreen. Adds individual harmonics up to the 40th, measured neutral current and advanced data-recording functions.
M4M 32: Higher-Accuracy Analysis
Front-panel touchscreen analyzer with individual harmonics up to the 63rd. ABB specifies Class 0.2S active-energy accuracy at 5 A. Confirm the exact input conditions and required accuracy against the technical documentation.
Current Inputs, Communication & Version Checks
M4M analyzers are not direct-connected current meters. Standard versions use 1 A or 5 A current transformers; dedicated Rogowski versions work with ABB R4M Rogowski coils. Match the analyzer to the sensor type and existing installation.
Communication choices depend on the order code. M4M 20 and M4M 30 include Modbus RTU, Modbus TCP/IP, Profibus DP-V0 and BACnet/IP versions; M4M 2X and M4M 32 include Modbus RTU and Modbus TCP/IP versions. Bluetooth is listed separately for commissioning. Do not assume one analyzer includes every protocol.
MID-certified versions are available within M4M 20 and M4M 30. Specify billing or certification requirements explicitly; MID approval does not apply to every M4M model. For M4M 2X, check the PQ/RTS package rather than assuming all recording and harmonic-analysis functions are included.
