Installs and grounds in less than 5 minutes Save time with quick and easy installation with the CV Series – 5 minutes or less.
  • One technician
  • One hole with standard Greenlee® punch
  • Panel door does not need to be removed
  • Grounds instantly to metal enclosure with patent-pending AutoGround™ process
  • Maintains panel arc test ratings up to 63kA when properly installed
Work more efficiently with Fluke ClirVu® CV400 95 mm (4 in) Infrared Windows
  • NFPA 70E processes significantly reduced due to less work permit requirements
  • Faster and more comfortable inspections because full PPE is often not required
  • Reduce the risk of arc-flash and electrocution, increase the safety of your personnel and reduce the time and cost of preventive maintenance
  • CV400 is Torture Tested™ to the highest arc blast test ratings IEEE C37.20.7: 63 kA Arc tested at KEMA, UL 50/50E/50V, UL1558, IEC60529-1: IP67, IEC 60068, NEMA 4/12, CSA C22.2 NO. 14-13:2012, and CE
  • Convenience of both quick turn or security keyed access

  • Be safer: Measure voltage to 1000 V ac through the open fork, without test leads.
  • Be faster: No need to open covers or remove wire nuts.
  • Be more efficient: Simultaneously measure voltage and current.
  • Be everywhere: 17.8 mm open fork is widest in the industry; measure up to 200 A on 4/0 wires (120 mm2).
  • Go beyond simple detection. Actually measure ac voltage and current values without test leads.
