Grace Engineered R-3W-2 Safe Side Voltage Indicators (Category Rated DIV 2)

Maker : Grace Engineered

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?


Applications:


  • Circuit Breaker Disconnects - No Visible Blades

  • High Energy Panels (NFPA 70e Category III and IV)

  • Frequently Accessed Panels

  • Mechanical LOTO: Indicating Zero Energy

  • Panels with Multiple Power Source



VoltageVision® thru-door power warning alerts provide electrical safety information while the panel doors are safely closed. This “one-size-fits-all” solution detects 3-phase AC or DC voltage from 40-750VAC/30-1000VDC. The encapsulated construction and redundant circuit design means rugged reliability. Voltage is the common denominator in an electrical accident or an arc flash; no voltage means no accident, no arc flash. While performing electrical LOTO with a thru-door voltage detector installed, the electrician can pre-check the internal voltage state without opening the enclosure. Next, the electrician should replicate a zero voltage reading with his voltmeter as per NFPA 70e 120.1(5). This low-cost, redundant voltage-verification task reduces arc flash risk and increases electrical safety for workers.
