An overcurrent protection system (102) may be used to protect electrical circuit components from damage or failure due to abnormally high currents. The system may include a current interrupter (110) electrically coupled between a power source (104) and an electrical load (106). The current interrupter is configured to interrupt at least a portion of a current flow between the power source and the electrical load based on at least one current interrupt characteristic of the current interrupter. The system may also include an analog circuit component (112) thermally coupled with the current interrupter. The analog circuit component is configured to generate heat in response to an overcurrent fault condition. At least a portion of the heat modifies the at least one current interrupt characteristic of the current interrupter.
