China 7T/12.5T factory and manufacturers

7T/12.5T

The surge protection device belongs to T1+T2+T3AC power surge protector,which isinstalled

between the power supply network and the equipment to drain,suppress and reduce the overcurrent

and overvoltage caused by induced lightning strikes or the power grid system,so as to reduce the

harm to the electrical equipment
