OSR Metal enclosures

Product description

OSR metal enclosures are designed for high currents up to several thousand amperes. They are made for industrial switchboards, energy distribution, reactive power compensation and in cases when it is necessary to use an enclosure with high mechanical strength.
Our series provides many configuration options and selection for appropriate equipment, even if it is extremely large and heavy.
The construction and customized solutions provide many assembly options, ensure high stability and high IP up to IP55, which is obtained by means of a special type of seal applied into the cavity. Normally, the enclosures are made of steel sheet, protected and powder-coated, and
- if necessary - some of them are made of stainless steel. Both solutions offer great application possibilities even in case of rough environmental conditions - corrosion or high levels of dust.
