- Item no: F23110557
- Weight: 0,06 kg
DIN rail mountable, single or three-phase energy meter
The Shelly Pro 3EM-3CT63 is a DIN rail mountable, single or three phase energy meter. It is supplied with a combined three-phase current transformer (CT), which is mounted directly above a circuit breaker. The Shelly Pro 3EM-3CT63 measures energy consumption accurately and can be used in many applications, such as monitoring industrial machinery, saving energy in homes or offices and managing electrical loads.
*IMPORTANT! This device does not have an integrated relay. A contactor is controlled via a Shelly Pro add-on, which is attached to the Shelly Pro 3EM-3CT63.

- External contactor control: Loads can be controlled based on device automation or scripts. Available with the additional Shelly 3EM Switch add-on
- Photovoltaic compatible
WHY you should choose the shelly pro 3em-3ct63
Professional energy meter
The Shelly Pro 3EM-3CT63 records both the accumulated energy and the instantaneous values of voltage, current, active power and apparent power per phase/channel in real time. It stores the data in non-volatile memory and enables it to be retrieved at one-minute intervals over a period of up to 60 days. It also has a real-time clock that ensures the time is always set correctly - even if the connection to an SNTP server is interrupted.
Functions
LAN, WLAN and Bluetooth connectivity
LAN connection for high security and reliability. Simultaneous use of WLAN and LAN, as a backup if necessary.
4-quadrant measurement
Measurement of capacitive and inductive load types of imported and exported active energy.
