Class 4

Electrically insulating Class 4 boots provide protection up to a maximum working voltage of 36000V. This gives the highest certified level of electrical protection available.

At time of writing there are currently no Class 4 dielectric boots available in the market. These are in development and information will be added here when they are available.
