Overview
About the Telephone and Data Line Surge Protector LP-C/RJ11.
The LP-C/RJ11 is a DIN-rail surge protector for telephone, data and control lines. Mounted on a 35 mm standard rail and connected through RJ11 sockets on its line and equipment sides, it protects the connected equipment against overvoltage arising from lightning strikes. Its multi-protection circuit combines a gas discharge tube (GDT) with a diode stage, limiting line-to-line voltage to below 350 V. A built-in 4 mm lifting grounding terminal gives strong wiring capability and a reliable ground connection, and the compact housing fits easily into existing panels.
Features
- 35 mm standard DIN-rail mounting for easy installation
- Multi-protection technology for strong protection and high reliability
- Built-in 4 mm lifting grounding terminal for reliable grounding
- RJ11 connection with 40 MHz transmission rate and ≤ 0.5 dB insertion loss
- Compact, flexible design in flame-retardant reinforced nylon (UL 94V-0)
- Wide operating temperature of −40 … 80 °C
Applications
- Telephone systems
- Computer networks
- Control systems
