LEADER® voltage protector is intelligent over voltage and over current automatic reclosing protector is a comprehensive intelligent protector that integrates over voltage protection. Under voltage protection, under voltage protection, over current protection. This product can immediately cut off the power supply to the product's electrical equipment from being burned out in the event of a fault, over current fault, etc. When the circuit returns to normal, the protector will automatically restore power. Over voltage value, under voltage value, over current value. The delay value of this product can be set by yourself. The corresponding parameters can be adjusted according to the actual situation of the user. It is widely used in occasions where the power system is unstable.
