Product Overview
The SZK-A IP66 enclosure is a premium, heavy-duty solution designed for outdoor electrical and industrial installations. Its sloped roof enhances drainage and prevents debris build-up, while the high IP66 rating ensures complete protection against dust and powerful water jets — ideal for harsh environments.
Constructed from Galvar-coated steel (Zinc-Aluminium-Magnesium) and finished in durable RAL7035 powder coating, this enclosure offers superior corrosion resistance, especially in C4-class environments with higher salinity or pollution levels.
Engineered and manufactured in Europe, the SZK-A enclosure benefits from ISO 9001, ISO 14001, and ISO 3834-2 certified processes, ensuring quality, durability, and compliance with relevant EU standards (EN 62208, EN 60529, EN ISO 12944-2).
