Spd Low Voltage Lightning Surge Protector Selection, Low Voltage Lightning Surge Protector And Other Spd Low Voltage Lightning Surge Protectors

Some applications require two or more surge protection device low-voltage lightning surge protectors to reduce the electrical stress of the protected equipment to an acceptable value (lower Up) and reduce the transient current in the building. According to the energy tolerance value of the two SPD low-voltage lightning surge protective device, in order to obtain an acceptable distribution of electrical stress, it is necessary to coordinate (in the same circuit, it is advisable to select a surge protector with automatic energy coordination function to achieve good coordination).
