oltageVision® 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 40-750V
AC/30-1000VDC.
The
encapsulated construction and redundant circuit design
means rugged reliability
. V
oltageVision® products are
available with flashing LEDs (R-3W) and non-flashing LEDs
(R-3W
-SR).
Safer Lock-Out T

Keeping personnel away from live voltage is foundational to
electrical safety
. Electrical safety demands a precise answer
to the question 'Is voltage present?'.
Thru-door voltage
indicators provide visibility of voltage from outside the
enclosure without exposing personnel to voltage.
More Productivity in Mechanical LOT
O
W
orkers performing mechanical LOT
O must isolate
electrical energy
.
An externally-mounted voltage detector
provides a means to check voltage inside an electrical
panel. Without a voltage indicator
, a mechanic performing
mechanical LOT
O would be required to work in tandem with
an electrician using a voltmeter to physically verify voltage
inside an electrical panel. In this case, the electrician is
exposed to voltage. With thru-door voltage detectors, the
mechanic can verify zero electrical energy without any
exposure to voltage.
Reduced V
oltage Exposure and
Arc Flash Risk
V
oltage is the common denominator in an electrical accident
or an arc flash; no voltage means no accident, no arc flash.
While performing electrical LOT
O 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 NFP
A
70e 120.1(5).
This low-cost,
redundant voltage-verification task reduces arc flash risk
and increases electrical safety for workers.
Disclaimer:
V
oltage indicators are a supplement, not a substitute, for establishing
electrically safe work conditions when working on potentially live electrical
conductors as per NFP
A
70E 120.1(1) to (6). Employers must also provide written
LOT
O procedures and the corresponding training that properly incorporates voltage
detectors into their safety programs [NFP
