安装应用 The NKP-TEL-2J series Power MODEM Signal Lightning Arresters are designed for lightning protection of various communication MODEM equipment (such as power line carrier communication ports) in power systems, effectively safeguarding these electronic devices against induced lightning surges. These arresters feature standard terminal block connections and are equipped with multiple interface converters including 10-pin sockets, 6-pin RJ11 jacks, and 8-pin RJ45 ports to accommodate diverse communication equipment interface requirements, providing comprehensive protection with ≤1ns response time, ≤100V residual voltage, and 10kA (8/20μs) surge current capacity per line while maintaining signal integrity through<0.3dB insertion loss across all interfaces in compliance with IEC 61643-21 standards for industrial surge protective devices.
