Along with the development of the electric power industry, our lives are in use every hour and moment, if there is no electricity, life will enter into a state of paralysis. However, with the widespread use of electricity in life, electric fire is also increasing, since the Self - resetting overvoltage and undervoltage protector began to be of concern. Double fire is because there is no use the protection of power line failure, so it can not be timely detection and maintenance. In order to protect the line, so now use the Self - resetting overvoltage and undervoltage protector is more and more used for the main function of duplex, in the process of using the effect is very significant.

1, since the Self - resetting overvoltage and undervoltage protector when voltage in single-phase circuit, duplex, can cut off the circuit very timely, can prevent the fault very good functional, so powerful, in which life is well ensured when the power line failure, since the over and under voltage protector the first time to cut off the power to avoid double fault, so the fault line and the voltage problem, can be checked in time, to avoid more serious consequences.

2, some people think that this kind of protection is not sensitive, so the idea is wrong, because since the compound over-voltage protection device sensitivity is very high, but there was some very tiny moments or temporary voltage fault in the line, the protector will analyze and judge according to the situation, not misleading, too will not affect the normal use of electricity. So it is very secure, don't worry about making mistakes, affecting the normal use, can be suitable for many occasions in power.

3, at the same time, if the voltage of the power lines is very high, the fault current is more obvious, so for the Self - resetting overvoltage and undervoltage protector, itself is not affected by any damage and damage, so the use is quite reassuring, action time in 1 seconds, so don't worry because of delay fault judgment and influence the accuracy, for this feature, since the over-voltage protection device can ensure the safety of all electric double, avoid failure and fire.

4, and, as it is used in the installation of guide rails, so Self - resetting overvoltage and undervoltage protector is practicability and beauty and the protection of duplex, installation is very convenient, do not spend a lot of manpower, but also in the process of using, it will not affect the beauty of the surrounding environment, since the Self - resetting overvoltage and undervoltage protector themselves rarely failure of duplex, can guarantee the working condition is very good in certain situations, life for all electricity provides very good protective effect, do not worry about every day because of a power failure and unstable circuit.
