| Abstract: | IEC60943 technical report was prepared by IEC technical committee 32:Fuses, and was issued in 1998.Technical report is intended for guidance in estimating the permissible values for temperature rise of component parts of electrical equipment carrying current under steady state conditions. Technical report supplies the calculation of contact resistance of electric contacts and the basic ageing mechanisms of contacts; the calculation of temperature and temperature rise of contacts and connection terminals; the maximum permissible temperature and temperature rise of various components, in particular the contacts, the connection terminals and the conductions connected to them ; the general procedure to be followed by IEC product committees for specifying the permissible temperature and temperature rise. |
