Martindale MARVI13800

Voltage Indicator

 



Product Overview


The Martindale VI13700 has been widely used for many years and as part of its design has always included a fuse in the probe to limit the current in the event of damage to the cable.

There is a technical argument that fuses in a voltage indicator can cause unreliability and any problem with the fuse could cause the voltage indicator not to indicate a hazardous voltage. In reality this risk is very small and correct proving procedures will identify the problem. None the less, because of this potential problem, BS EN61243-3 prohibits the use of fuses in 2 pole voltage indicators.

NB Proper proving procedures should always be used with any voltage indicator.
