Grace R-3W Voltage Indicator
Grace R-3W voltage indicator. Grace Engineering R-3W voltage indicator aids in the detection of phase loss in industrial equipment.
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?
