- Voltage measurement and configurable alarm reports
- Included 3x Current Transformers 120A
What is Shelly 3EM?
Shelly 3EM will help you get enhanced safety and everyday control over appliances or machinery, along with the ability to make smart decisions about electrical consumption, thanks to its WiFi connected energy measurement technology and 10 amp contactor control, monitoring up to three phases between 110 and 240v per line.
What can Shelly 3EM do for you?
With 365 days energy consumption data free Cloud storage, Shelly 3EM allows you to monitor and analyze the consumption of each circuit, appliance, or of your whole home to optimize energy usage.
You can export the data in CSV format and get detailed statistics.
Calculate the precise cost for production and measure the exact working time of each machine. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor. Avoid any additional expenses or drastic drops in voltage which may cause damage. If a machine is on during non-working hours, Shelly 3EM can switch it off.
Shelly 3EM will automatically shut down and inform you when the preset consumption limit is exceeded. This way, you can make sure that you don't spend more monthly than planned.
Overheating protection embedded in the device avoids any load from damaging the device or your appliances.
- Standard warranty (included in purchase price): 24-month manufacturer's warranty due to device malfunctions when it is used in user manual described conditions.
While this is technically user-installable in many locales, we recommend consulting a licensed electrician to install automation components - in addition to being licensed to work with electrical devices, they are also familiar with local building codes.
- Manufacturer's note: Each Shelly device emits heat under load. Do not combine two or more Shelly devices stacked on top of each other in a confined space. There must be a minimum distance of 1 cm between them to allow for airflow.
