The new connection box OK650 produced by Korner, with Registered Design, for the professional refrigeration market (refrigerated counters, freezer showcases, cellars) is deeply innovative compared to what already available on the market. Although it has standard dimensions, it offers more space inside for the cabling of the electric cables. The most important news is the possibility to precabling the cables on the tabs 6.3×0.8 mm and afterwards fixing them inside the connection box just pressing them onto the plastic pins, with a considerable process easiness for the users. The pins also allow the eventual following removing of the fastons in case of new wiring operation. The connection box OK650, with IMQ and cULus certifications pending, is produced in two versions: one in plastic UL94V2 with T85 °C and the other one in PA6.6 UL94V0 with T140 °C, both no-flame on piece compliant with the regulation EN60335-1, GWT750° in 2’ sec. (EN60695-2-11).
