The mild steel single door combinable floor standing enclosure range, MCS-3R, with a IP 55 and TYPE 3R protection degree, is available off the shelf in many different sizes. This enclosure range is well suited for many different applications. The risk for component failure, and with that unnecessary downtime, is eliminated as water and dust are prevented from entering the enclosure. To prevent oxidation in 3R environments, all hardware has been changed to stainless steel or received additional plating.
