Expected Life And Failure Mode Of Spd Low Voltage Lightning Surge Protector

(1) The expected life of SPD low-voltage lightning surge protector: mainly depends on the probability of a surge exceeding the maximum discharge capacity of the SPD low-voltage lightning surge protective device; the actual life may be shorter or longer than the expected life, depending on the actual frequency of the surge. In specific application cases, the expected life of SPD low-voltage lightning surge protector with higher Imax is greater than that of SPD low-voltage lightning surge protector with lower Imax, as long as it does not exceed the tolerance limit of the SPD low-voltage lightning surge protector;

(2) Failure mode of surge protection device low-voltage lightning surge protector: The failure mode itself depends on the type of surge and overvoltage. If you want to avoid power supply interference or interruption, it is necessary to equip the SPD low-voltage lightning surge protector with a dedicated backup protector SSD;
