LDY-RJ11 lightning protection device are applicable to the signal protection of the telephone dialing equipment, which can prevent the system or device from permanent damage or transient interruption arising from inductive overvoltage, overcurrent and the other transient surge voltage caused by lightning or industrial noise. so they are widely used to against lightning in electronic
communication system device,such as telephone,fax,program control machine room,etc.
