6A Three Phase Voltage Monitoring Relay for electric motors voltage control relay

6A Three Phase Voltage Monitoring Relay for electric motors voltage control relay
 
The power distribution boxes used in the past and currently in use have no protection functions such as overvoltage, overvoltage, undervoltage, short circuit, etc. The voltage is too high and the appliances are burned. In today's dramatic increase in home appliances to the countryside and residential electrical appliances, the terminal supply facilities (capacity of transformers and wires) remain unchanged, and the increasingly harsh natural environment and social environment (theft of wire thief stealing wires) lead to large areas burning. The situation of bad electrical appliances is happening every day in all parts of the country. Once it happens, the losses are heavy, the claim is nowhere, the workforce and people’s financial affairs come one after another.
 
The guarantee of safe, scientific, and intelligent power supply can ensure that the appliance is not burned, burned, or caught fire due to an abnormality in the power grid voltage or input power supply, effectively protecting the safety of life and property. Multiple protection, self-protection at high voltage, stable operation at low voltage, accurate operation voltage, delay time for start-up, fast execution response; real-time voltage display; data can be changed according to the rated voltage of different appliances; can be set to power failure Re-call and trip power-off protection automatically open or manually open manually; can set the closing delay time; can be a key to restore the factory settings; can test the machine trip, closing, automatic, manual, delay, etc.; can be directly connected Into the 380V phase line for high voltage testing
