New HV3 Class 3 Dielectric Boots from Workmaster™

Workmaster Class 3 Dielectric Boots HV3

Our new dielectric Class 3 safety footwear provides protection to a maximum working voltage of 26.5kV to EN 50321-1:2018. This new standard was introduced for insulating footwear for live working and published in 2018, replacing EN 50321:1999. Dielectric Class 3 safety boots are suitable for use in environments with a maximum working voltage of 26.5kV.

Available now, our Class 3 electrically insulating HV3 dielectric boots will keep you safe and comfortable when working in environments with high voltage hazards. They have a lightweight design, with a high-visibility green HV3+ compound shaft on a slip-resistant vulcanised rubber sole (HV3+). Our HV3 boots allow live working up to 26.5kV with every boot tested at 30kV; ideal for power and substation operations, electrical installations and electrical hazards in wet conditions.
