An "electrically safe work condition" is critical for electricians performing maintenance on de-energized systems. The VoltageVision™ R-3W is a hardwired voltmeter or voltage detector connected to the main disconnect or circuit breaker, and flashes whenever hazardous voltage is present in any individual phase. Reduces arc flash by pre-verifying electrical isolation from outside the panel.

Voltage is the single determining factor if an electrical accident or an arc flash is possible--No voltage means: No accident, No arc flash.
After disconnecting power to an enclosure, electricians can "pre-verify" voltage while the enclosure is safely closed. The risk of arc flash will be reduced because electricians know if there is power inside the enclosure, before re-verifying isolation with a meter.

Unmatched Reliability due to dual redundant circuitry and no separate power supply. The R-3W voltage detector is powered from the same “voltage” that it indicates.
