TRSX-Three phase/20

TRSX-Three phase/20 is applicable to low-voltage power supply and distribution system with power grid voltage below 1000V and frequency of 50/60Hz. It is connected to the power line of three- phase power supply and distribution system in parallel to prevent damage to power supply system and electrical equipment caused by impulse surge and transient overoltage caused by lightning stroke. This product has the advantages of large reserve current capacity, up to a level of 15kA (10/350us), safety and relibility, reasonable structure, and convenient installation.At the same time, it is designed with Kevin wiring method to ensure the best protection effect on the power supply system. This power supply lightning protection box is widely used for lightning protection and overvoltage protectionof the main power supply in communication equipment rooms, computer rooms, communication, power, factories, mines, finance, civil aviation, railway s, and other systems.
