Shelly Pro 3EM-3CT63 energy meter

Shelly Pro 3EM-3CT63 next-generation DIN rail mountable single- or three-phase energy meter with a combined 63A, three-phase current transformer.

The Shelly Pro 3EM-3CT63 accurately measures energy consumption and can be used in many applications, including monitoring industrial machines, saving energy in homes or offices, and managing electrical loads.

IMPORTANT! This device has no built-in relay. The contactor is controlled via a Shelly Pro add-on connected to the Shelly Pro 3EM-3CT63.

• 4-quadrant measurement
  
• DIN rail mounting
  
• Various connection options: Single- or three-phase installations
  
• Current transformer connection: Non-contact measurements
  
• Optical pulse display of energy consumption
  
• Real-time clock: Stored data retains correct timestamps even if the internet connection is lost.
  
• Datalogs: Data for up to 60 days is stored on the device and can be retrieved later.
  
• Control of external contactors: Loads can be controlled based on device automation or scripts. Available with the additional Shelly 3EM Switch add-on.
  
• Compatible with photovoltaic energy

The Shelly Pro 3EM-3CT63 records both accumulated energy and instantaneous values of voltage, current, active power, and apparent power per phase/channel in real time. The data is stored in non-volatile memory and can be retrieved for up to 60 days with one-minute intervals. The meter also features a real-time clock that ensures the time is always correctly set, even if the connection to an SNTP server is lost.

• LAN, wifi, and Bluetooth connectivity: LAN connection for high security and reliability. Simultaneous use of wifi and LAN as backup if needed.
• 4-quadrant measurement: Measurement of capacitive and inductive load types of imported and exported active energy.
• Accuracy class B (active energy): The Shelly Pro 3EM-3CT63 has a measurement accuracy of 1 percent.
• Power measurement: Monitors single-phase electrical systems with up to three measurement points simultaneously. Fast notifications and at least 60 days of 1-minute recordings are stored.
• MODBUS support: Enables quick and easy integration into existing industrial facilities.
