Given a switchgear and two different types of contacts and changeing the material of the crankcase to metal rather then using plastic. There are some limits the IEC has set, with the given changes try to improve the heat transfer from the conductive path to the surrounding air. A experimental design is presented, such that the experiment shall be reproducible. The sliding and braided contact are evaluated up against each other, to see which design is the best, by the best, which one can pass the IEC limits. the conclusion is that sliding is better then the braided connection. The sliding connection with the crankcase of aluminumis the closest one to pass the IEC limits, with the improvements done to the crankcase.
