A: See differentiating factors between the Voltage Indicators below.
R-3W – Most Common with flashing LEDs
R-3W-SR – Same as the R-3W but with solid red/non-flashing LEDs
R-3WA-RA – Same as the R-3W but with amber colored GND LEDs
R-3W2 – Blue face voltage indicator for hazardous locations
R-3F2 – Fiber optic voltage indicator, for hazardous locations and where dead-front (no voltage) panels are needed
R-3D2 – Flex mount for motor disconnects. Mounts in M20 or 3/4" knockouts. For use in hazardous locations
R-1V – Medium voltage indicator, used where voltages are between 2kV and 43kV
