                                            Combined Category D, C, B tested protector (to BS EN 61643) suitable for most
                                            twisted pair signalling applications. Available for working voltages of up to 6,
                                            15, 30, 50 and 110 Volts. For use at boundaries up to LPZ 0 to protect against
                                            flashover (typically the service entrance location) through to LPZ 3 to protect
                                            sensitive electronic equipment.

          •  Full Mode design capable of handling partial lightning    •  Colour coded terminals give a quick and easy installation
           currents as well as allowing continual operation of    check - grey for the dirty (line) end and green for the clean
           protected equipment                                 end
          •  Repeated protection in lightning intense environments  •  Screen terminal enables easy connection of cable screen
          •  Low in-line resistance minimizes unnecessary reductions    to earth
           in signal strength                                 •  Substantial earth stud to enable effective earthing
          •  Strong, flame retardant, ABS housing             •  Integral earthing plate for enhanced connection to earth
          •  Supplied ready for flat mounting on base or side  via a OVR CME kit


          Application                                         Installation
          Use on twisted pair lines, e.g. those found in process    Connect in series with the data communication or signal line
          control equipment, modems and computer              either near where it enters or leaves the building or close to
          communications interfaces.                          the equipment being protected (e.g. within its control
                                                              panel). Either way, it must be very close to the system’s

          Slim Line (OVR SL) and ATEX (OVR SLX) versions are also available. If your system requires a protector with a very low resistance or higher current, see the
          OVR E & H Series. Also use the OVR E Series for systems needing a higher bandwidth. Protectors for 3-wire (OVR SL/3W) and RTD (OVR RTD, OVR SL RTD) are
          available, as are the space saving protectors (OVR Q, OVR SL Series). The OVR KT and TN Series are additional protectors specifically for telephone lines.
