Product Description

Product description:
Lntroductions:
Three-phase over-voltage under-voltage protector is an important protection device for electrical equipment, which is mainly used to monitor the key parameters of three-phase power supply system, such as voltage, phase sequence, missing phase and phase balance. It can timely detect and deal with electrical power generating system and equipment safety may be faced with abnormal conditions, such as over-voltage or under-voltage, so as to send an alarm signal and take appropriate measures, such as disconnecting power, to prevent equipment damage and ensure the safety of electricity

Function:
Real-time display of voltage and current. Allows the user to clearly understand the working state of the motor.
Lack of protection. If the motor is missing phase, the protector will trip within 3 seconds to prevent the motor from burning due to lack of phase.
Overload protection. When the current is too large, the protector can prevent the motor from burning.
Current regulation. The user can adjust the current size according to the actual situation.
Timing off function. The protector has a timing off function, which can automatically power off on time.
Short circuit protection. Prevent short circuit of the line to further protect the motor.
Call tripping function. After the power grid is cut off, the switch will not trip, and after the power grid is energized, the switch will trip instantly, increasing the protection level.
Power on self-test function. The protector automatically detects the overvoltage, undervoltage, leakage, short circuit and other faults at the output and input terminals to prevent accidents.
Water immersion protection against electric shock. When the leakage current value reaches or exceeds the set value, the protector will automatically disconnect the power supply to ensure personal safety.
Overvoltage and undervoltage protection. When the input voltage is above or below the set value, the protector will automatically shut off and issue an audible warning until the voltage returns to normal.
Earth leakage protection. When the supply current is more than or equal to 3 times the rated current, the protector will trip in a short time to cut off the supply.
Automatic reclosing function. After the above fault is detected and tripped, if the fault has been eliminated, the protector will automatically reclose the power supply after a certain time interval
