Shelly Current Transformer 120A



  • Standard warranty (included in purchase price): 24-month warranty through manufacturer 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.
