## Summary description

Carlo Gavazzi EM330 is a 3-phase power meter for monitoring electrical parameters in low-voltage networks. It supports 400V nominal voltage with a 5A input range, features an LCD for local readings and an RS485 Modbus port for remote data acquisition. MID certification ensures compliance for billing/verification. Suitable for energy monitoring, submetering and building automation.

## Long description

Carlo Gavazzi EM330 is a three-phase power meter designed for monitoring electrical energy and key electrical parameters in low-voltage installations. Intended for use on 400 V nominal networks with a 5 A input range, the device provides local measurement readout via an integrated LCD and supports remote data exchange through an RS485 Modbus interface. MID certification makes the EM330 suitable for verified energy measurement and submetering where regulatory accuracy is required.
Advantages
The EM330 combines compact DIN-rail mounting with a clear LCD display for rapid local checks and an RS485 Modbus port for integration with building management systems or data acquisition equipment. Its three-phase measurement capability includes active energy and common electrical parameters, enabling both monitoring and billing use. MID certification confirms compliance with European metering accuracy requirements, while the 5 A input range supports direct connection to many distribution circuits or use with compatible current transformers.
Suitable for
Energy monitoring and submetering in commercial and residential buildings
Integration with building automation and SCADA systems via RS485 Modbus
Verification and billing of electrical consumption where certified metering is required
Monitoring of three-phase circuits in distribution panels and tenant metering
Key specifications
Measurement type: three-phase active energy and electrical parameters
Nominal voltage: 400 V (three-phase networks)
Input current range: 5 A (direct connection or with external current transformers)
Display: integrated LCD for local readout of values and menus
Communication: RS485 interface with Modbus protocol for remote reading and integration
Accuracy/approval: MID certified for verified billing and trade-use measurement
Mounting: DIN-rail for electrical distribution cabinets
How to use
Install the EM330 on a standard DIN-rail inside the distribution board and make the voltage and current connections according to wiring diagrams and local electrical codes. Use the integrated LCD to view instantaneous values, cumulative energy, and configure basic settings. For remote monitoring, connect the RS485 Modbus port to the building management system or data logger and configure communication parameters (address, baud rate, parity) to match the host. When using current transformers, ensure correct CT ratios are entered in the meter settings to obtain accurate readings.
Usage recommendations
Follow local electrical regulations during installation and commissioning. Verify CT polarity and phase sequence to avoid measurement errors, and perform an initial comparison against a reference meter after installation. Use properly shielded cabling for RS485 connections and set communication parameters to prevent data loss in larger networks.
