Insulating material

WAGO primarily uses polyamide (PA66 and PA46) for housing current-conducting parts, as well as polyphthalamide (PPA) and
polycarbonate (PC) for insulating material (see table). For more than 40 years, these materials have proven themselves in
WAGO products and all are approved by the responsible test authorities.
