The Sonoff POWCT is a smart consumption meter with a current converter, which also has a built-in relay suitable for switching a small current (max. 2A). Thanks to this, it is able to control the pull-in coil of a high-current contactor installed in a distributor.

The measuring range of the POWCT is between 0-100A. Thus, it is also suitable for measuring the spine of apartments or houses. The design of the module can be mounted on a DIN rail, faithful to the Sonoff POW series, and has a display and a microswitch suitable for pairing and relay switching.

Thanks to its external WiFi antenna, it can even be installed in a metal cabinet. By placing the antenna outside the metal cabinet, it will be able to communicate with the WiFi router.

The device has a microswitch with which it can be paired with the eWeLink application, and with this microswitch it is also possible to change the status of the relay output.
