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 a wide range of applications, including monitoring industrial machinery, saving energy in homes or offices, and managing electrical loads.

IMPORTANT! This device does not have a built-in relay. The contactor is controlled by 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: Up to 60 days of data is stored on the device and can be retrieved later.
  
• External contactor control: Loads can be controlled based on device automation or scripts. Available with the 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 at one-minute intervals for up to 60 days. The meter also features a real-time clock that ensures the time is always set correctly, even if the connection to an SNTP server is lost.

• LAN, Wi-Fi, and Bluetooth connectivity: LAN connectivity for high security and reliability. Simultaneous use of Wi-Fi and LAN as a 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 metering: Monitors single-phase electrical systems with up to three measuring points simultaneously. Fast notifications and at least 60 days of 1-minute recordings are stored.
