Abstract

Described herein are methods and systems for efficiently and accurately distinguishing between the current characteristics associated with inrush current and the current characteristics associated with a short circuit. In particular, the techniques described herein allow a circuit breaking system (also referred to as a circuit breaking device) to tolerate the conditions associated with inrush current while maintaining the ability to detect and responsively mitigate conditions associated with a short circuit. In some cases, the circuit breaking system evaluates the current characteristics of an input signal generated by a power supply in order to drive an industrial device, such as a motor. In such cases, the circuit breaking system acts as an intermediary between the power supply and the industrial device, and under certain circumstances, the circuit breaking system interrupts the flow of electrical energy (i.e., the input signal) to the industrial device, thereby tripping the circuit breaking system.
