## Long description

ProBase 3F-ESH-4ML MODBUS RTU is a three-phase electricity meter designed for DIN-rail mounting that provides accurate measurement of active electrical energy in three-phase installations. Equipped with MODBUS RTU communication, the meter enables remote reading and integration with building management systems and industrial controllers. Its compact form factor and standardized electrical inputs make it suitable for use in commercial, industrial and residential distribution panels where centralized energy monitoring and data logging are required.
Advantages
The meter offers reliable three-phase active energy metering with remote access via MODBUS RTU, enabling centralized data collection and automation. Its DIN-mount design simplifies installation in standard switchboards and reduces panel space. The device supports stable measurement across typical supply conditions and is compatible with common building automation systems, helping to streamline energy monitoring and reporting workflows.
Suitable for
Centralized energy monitoring in commercial buildings
Industrial power distribution and consumption tracking
Residential and multi-dwelling unit energy submetering
Integration with SCADA and building management systems via MODBUS RTU
Key specifications
Measurement type: three-phase active energy (kWh)
Mounting: DIN-rail (standard profile)
Communication interface: MODBUS RTU (serial protocol)
Input: direct connection to three-phase systems (voltage and current inputs as per product category)
Display: integrated local display for on-site reading
Accuracy class: suitable for commercial/industrial monitoring (refer to manufacturer for exact class)
Operating environment: typical indoor electrical distribution panel conditions
How to use
Install the meter on a DIN-rail inside the electrical distribution panel and connect the three-phase voltage and current inputs according to the wiring diagram supplied with the device.
