The Dragino LC01 is equipped with over-current, over-voltage and short-circuit protection to effectively prevent lightning strikes. The LC01 body is made of fire-resistant polycarbonate with the addition of an anti-ultraviolet material that does not change color under the influence of external factors.

The LC01 has a zero-crossing trip function to avoid sparks caused by voltage fluctuations and extend the life of the LC01 and controlled devices. Users can switch sockets on the LoRaWAN server.
