Phoenix Contact MM-EE-EEM-EM357 Three-Phase Energy Meter 100 A RS-485 MODBUS Pulse Outputs

The Phoenix Contact MM-EE-EEM-EM357 (Part No. 1744495) is a three-phase energy and power measuring device designed for industrial energy monitoring and control systems. It directly measures active power in three-phase networks up to 480 V AC and 100 A per phase with high precision, making it suitable for load tracking, efficiency monitoring, and power management in factories, commercial buildings, and industrial installations.

Featuring a clear LCD display with white backlighting, the unit shows real-time energy values and other electrical parameters. It supports Modbus/RTU communication over an RS-485 interface and provides two opto-isolated pulse outputs for integration with data loggers, building management systems, or automation controllers. The meter is MID-certified for compliance with energy billing and reporting standards.

Built for robust performance, this DIN-rail-mount unit operates in a wide ambient temperature range up to +70 °C, with IP51 front protection and IP20 connection enclosure rating for safe, long-term installation.
