In the world of low-voltage electrical installations, protecting cables against the thermal effects of short-circuit currents is non-negotiable. IEC 60949 – formally titled "Calculation of thermally permissible short-circuit current, taking into account non-adiabatic heating effects" – is the international benchmark for these calculations.
Unlike the simplified adiabatic method (often using the formula ( I^2t = k^2S^2 )), IEC 60949 introduces a correction factor that accounts for heat dissipation to the insulation and surrounding materials during a short circuit. This leads to more economical and realistic cable sizing.
