Telephone and Data Line Surge Protector LP-C/RJ11

Model LP-C/RJ11

LP-C/RJ11 DIN-rail surge protector that protects telephone, computer network and control system lines against lightning overvoltage, with RJ11 connections, 2.5 kA line-to-ground nominal discharge current and a built-in grounding terminal.

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
