The network switch surge protector is designed for communication line network devices or equipment. This surge protection device stands for DC voltage which is available for many ports i.e., 4, 8, 12 and 16. This switch surge protector works for the protection of telecom devices and make a guarded shelter for high data rate operating equipment. The TCP/IP network also include the surge risks in their circuits which can be eliminated by installing the same. The device is tested as per IEC 61643-21 standard that can bear minimum 5kA fault current. The protection degree for network switch surge protector is IP20. The voltage level in electric circuits also get into the balance by equipping the network switch surge protector.
