IEC 61643-11 Annex A specifies Max Continuous Operating Voltage (Uc) as 255 VAC. IEC 61643-11 test procedure limits maximum Impulse Current (Iimp) to 10kA due to internal product safety fusing. IEC 61643-11 recommends a maximum preferred value for Nominal Discharge Current (In) of 20 kA. IEC 61643-11 Temporary Overvoltage tests are passed in withstand mode. Upstream overcurrent protection not exceeding Rated Load Current (IL) shown above must be installed ahead of the surge reduction filter.
