The K curve is designed for motor and inductive loads where short inrush currents must be tolerated without nuisance tripping — think contactor coils, small transformers, or solenoid valves in a control panel.
The K characteristic defines the magnetic trip threshold — typically 8 to 12 times the rated current — which allows it to pass the high inrush of motor-starting currents while still protecting against short circuits.
