VoltageVision®
Electrical safety demands that we know the answer to one question: Is there voltage? A wrong answer can have severe consequences. The VoltageVision® (R-3W) is a reliable tool that helps answer that question. Typically hardwired to the load side of the disconnect or circuit breaker, the Voltage Vision® (R-3W) flashes whenever hazardous voltage is present in any individual phase.After disconnecting power to an enclosure, electricians can pre-verify voltage isolation while the enclosure door is safely closed. The risk of arc flash is reduced because electricians know if there is power inside the enclosure before re-verifying isolation with a meter.
The Voltage Vision® (R-3W) is unmatched in its reliability due to its dual redundant circuitry and no separate power supply. Voltage Vision® (R-3W) gets its power from the same voltage that it indicates! Ask this question: Can you live without it?

A message from Phil Allen about Short Circuit Current Ratings on the VoltageVision:
"A Short Circuit Current Rating (SSCR) on a device tells the user how much instantaneous current it can pass without permanent damage. A SSCR has nothing to do with the failure mode of the device, but rather its response to high amounts of current during a short circuit event somewhere in the system. Unless a device switches or conducts higher currents under normal operation, it would be largely unaffected by a short circuit (except for collateral damage from heat or surges)
The VoltageVision® R-3W is a unique device because it is wired between all three phases and is effectively ﾑshort circuitingﾒ all the phases. Under normal circumstances this device allows only 100-200 micro Amps to pass between each phase and ground. If a short circuit occurs in a system where an VoltageVision® R-3W is installed, the high currents that pass through the system would not find a path through the VoltageVision® R-3W and would not cause any damage to the device. Therefore the SSCR rating is not applicable for the VoltageVision® R-3W."
