The R-3W series provides visibility of voltage using flashing (R-3W/2) and non flashing (R-3W-SR) LEDs to visually verify zero electrical energy without any exposure to voltage inside the electrical panel.

  • The Voltage Test Station (VTS) is a Permanent Electrical Safety Device that allows workers to quickly and safely validate zero electrical energy from outside the electrical enclosure.
  • The VTS combines a voltage indicator and test points to confidently verify zero electrical energy.
