The overvoltage protector is an essential protective device in household circuits. By installing an overvoltage protector in the circuit, the voltage the circuit can be maintained within the fluctuation range of the rated voltage of the appliances. This range is usually the critical value of the insulation strength and voltage endurance all appliances. If the actual voltage in the circuit exceeds this range, it will cause the appliances to catch fire, leading to fires and losses. However, thevoltage protector can control the voltage in the circuit within a certain range, keeping the voltage in the household circuit below 240V (the critical value the appliance’s voltage insulation), thus providing a certain level of protection for the circuit.

  The purpose and function of overvoltage protectors

  The overvoltage protector is mainly used in household circuits. Since it can maintain the voltage in the circuit at a relatively stable level it provides a certain degree of protection for the electrical appliances in the circuit, which is the main function of the overvoltage protector. In the circuit, electrical are often damaged by instantaneous overvoltage caused by abnormal power supply from the grid. In a very short time, the appliances in the circuit are the first to affected and are often damaged, especially those that are working normally. However, devices like circuit breakers react slowly and often trip only after the appliances have been damaged which is very unfavorable for the stability of the circuit. On the other hand, the overvoltage protector can provide protection for the circuit in the first time according the fluctuations in the circuit voltage, diverting part of the current to flow into the overvoltage protector for consumption. This reduces the voltage in the circuit to a normal working state.

   In addition, the overvoltage protector can adjust the data according to the rated voltage of different electrical appliances, so as to avoid the situation the overvoltage protector cannot work normally due to the difference in the rated power of the appliances in the circuit. In general, the overvoltage protector will protect the electrical appliance with the lowest rated voltage in the circuit, so as to maintain the safety of all appliances in the circuit and make the circuit’s working state stable.

Features of overvoltage protectors

  The overvoltage protector can control the voltage in time, maintaining circuit safety, and can monitor and protect the entire circuit comprehensively. It not only be installed in the household circuit breaker box but also used separately, which is very convenient. The overvoltage protector can also withstand high voltage, has safety performance, and is quite durable. The overvoltage protector can also combine manual control with automatic control, has a wide range of applications, and is highlyable.
