Double LED display: SVP916 protector can display actual measured voltage and current. Protectors are available in 40A, 63A and 80A resistive load, not the same current load, depending on each 's actual use need. Home usage over or under and current protection: It is mainly used for residential household box entry or over-voltage, under-voltage or over-current protection of distribution lines for single-phase electrical equipment. Adjustable voltage current protector and reconnecting time: Overvoltage value, undervoltage value, overcurrent protection and fault recovery delay time are adjustable. Precautions for use: Please pay attention to the maximum protection current value of the protector, the zero line N of the protector is directly connected, and there is no disconnection function. When the undervoltage breaking time is greater than 0.3 seconds, the voltage protector will not open after power failure. Automatic recovery connecting: Its main feature is when the circuit has over-voltage or under-voltage, over-current problems, the protector can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides,the protector can automatically turn on the power supply when the circuit voltage s to the normal.
