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
