Carlo Gavazzi EM530
The EM530 is a three-phase energy meter from Carlo Gavazzi designed for use with external current transformers (CTs). It is suitable for monitoring higher-current circuits where direct connection is impractical.

HARDWARIO Integration
The EM530 is used in industrial energy monitoring applications with HARDWARIO:
- GAUGER: Reads three-phase power data via Modbus RTU and sends it to HARDWARIO Cloud for analysis.
- Submetering: Monitoring energy usage per production line, machine group, or floor.
