touch protection according IEC/EN 62305-3.2 Protection against dangerous touch voltage
The isCon® conductor Pro+ can used as
protection against dangerous touch voltage.
The isCon®
conductor Pro+ was tested a
length max. Here the current flows between
the person's feet through their body. These voltages need reduced
via potential control insulation. This is
particularly required areas with groups people.
Here the current flows from the hand the foot
through the body. Both types voltage can harm-

The step voltage the voltage between person’s
feet placed apart.6
