Descriptions:

1)TP-1502-10P3G MDF over-voltage protection magazine is used for LSA modules, which forms the protection circuit for the protection of exchange room equipments and personnel against over voltage, for mainly as follows: 
2) The surge voltage caused by lightning on or around the outside lines. 
3) The short-time AC voltage inducted on external lines, when the power line, the power system or the electric railway system is broken down in the neighborhood of the outside line. 
4) The outside line directly collides against a 220 V power line. 
5) The housing of the magazine is flame retardant, high temperature resistance and aging resistance. It is 10 pair modular design magazine.
