IEC 60949, titled "Calculation of thermally permissible short-circuit currents, taking into account non-adiabatic heating effects," is published by the International Electrotechnical Commission (IEC).
When a short circuit occurs, a massive amount of current flows through cables and conductors.This current creates rapid, intense heat.If the temperature rises too high, it will permanently damage insulation and melt conductors.IEC 60949 provides the mathematical framework to calculate exactly how much short-circuit current a component can handle over a specific time before failing.
