There are five types of sub-racks in the Ripac family. The modular concept of Ripac sub-racks facilitates a wide range of application options with a minimum of components. All Ripac sub-racks are based on the same horizontal rails and system components. The difference lies in the design of the side panels and installation options. The sub-racks are shock and vibration-tested and comply with IEC 60 297-3-101, -102, -103.
