Series 3414 data line protectors Description Applications Protective devices for symmetric twisted pair data lines HUBER+SUHNER data line protectors have been designed to protect sensitive high speed data-, voice and multimedia application over copper lines against damaging transients caused by natural events such as lightning or man made surges. The protectors have been optimized to provide data transmission for several physical layers with bandwidth Cat 5 in channel class D and Cat 6 in channel class E. Possible interconnections are made via the industrial standard RJ45 connector and the devices are suitable for screened (STP) or unscreened (UTP) twisted pair cables or multi-core cables. Some protectors are suitable for use with Power over Ethernet (PoE according to IEEE 802.3bt). Series 3414 are designed for the protection of current and future sensitive data networks. The most important and frequently used devices are switches, multiplexers and cross-connects, hubs (also WLAN hubs), modems and network interface cards. The placement of DLP is in series between the incoming data line and I/O port of the equipment to be protected. For an effective protection we recommend to install the DLP on both ends of data lines. • Ethernet lines • AISG based antenna systems Typical residual pulse for series 3414 test pulse according to IEC 61000-4-5 1.2/50 µs 4 kV; 8/20 µs 2 kA: Residual pulse voltage: typ. 25 V Residual pulse energy: typ. 50 µJ Residual Voltage (V) 25 20 15 10 5 0 -5 -5 0 5 10 15 20 25 30 35 40 45 50 Time (µs) 76 HUBER+SUHNER Lightning protection
