It can be remotely controlled by Smart Life App for automatic closing and opening , have parameterized and configurable functions which can be automatically judged by MCU ,realizing the function of opening the circuit breaker when power outage and automatically closing when power on. Currently widely used in photovoltaic grid-connected AC distribution boxes , as well as the following occasions, including places that are difficult for personnel to access , places where maintenance personnel cannot be in place in time, unattended occasions, and places with high requirements for power supply continuity.
1. Equipment installation, maintenance and replacement must be completed by qualified electricians.
2. Repairs to the equipment are prohibited.
3. All applicable local, regional and national regulations must be followed when installing, using,maintaining
and replacing equipment.
4. If the device is found to be damaged when unpacking, please do not install it.
5. The company is not responsible for any adverse consequences caused by failure to comply with the in-
structions of this document and the documents mentioned in the article.
