Introducing the Shelly Pro 3EM-400: a versatile DIN rail mountable three-phase energy meter. With LAN connectivity and gen2 firmware, it offers professional integrators flexible solutions. It tracks accumulated energy, voltage, current, active, and apparent power per phase in real time. Data is stored for up to 60 days in non-volatile memory, accessible at 1-minute intervals.

Equipped with a real-time clock, the device ensures accurate timekeeping even if the connection to an SNTP server is lost. Users can remotely access, set up, and monitor the device, while it seamlessly integrates with automation systems within the same network infrastructure.

Featuring an embedded Web Interface, users can easily monitor, control, and adjust device settings.

Features

4 Quadrant measurement
DIN rail mounting
Multiple connection types
Current transformer connection
Phase sequence error detection* (option)
Channel-to-channel calibration**
No load threshold***
Optical pulse indication of energy usage
Real-time clock
Data logs
Accuracy Class B (IEC 62053-21)
Photovoltaic ready

* The Device has phase sequence error detection circuits. This detection works on phase voltages and considers only the zero crossings. The regular succession of these zero-crossing events is Phase A followed by Phase B followed by Phase C. If the sequence of zero-crossing events is, instead, Phase A followed by Phase C followed by Phase B, then a phase_sequence error is reported when the Phase sequence error detection option is enabled.

** ** At least 5000 W load is required for each channel.

** In case the total load for the three channels drops below 30 VA per channel the measured power level will be displayed, but no consumed energy will be accumulated to the energy statistics and a No load threshold notification will be displayed in the Device web interface and the mobile application.

Outputs

LED indication
Power: Red light if the power supply is connected.
Wi-Fi (varies):
Blue light if in AP mode.
Red light if in STA mode, and not connected to a Wi-Fi network.
Yellow light if in STA mode, and connected to a Wi-Fi network. Not connected to Shelly Cloud or Shelly Cloud disabled.
Green light if in STA mode, and connected to a Wi-Fi network and the Shelly Cloud.
The LED will be flashing Red/Blue if OTA update is in progress.
LAN: Green light if LAN is connected.
Count: Red light will be flashing when the Device is measuring energy according to settings with frequency dependent on the energy flowing through the measured circuit.
