Operation Detection Devices Having a Sensor Positioned to Detect a Transition Event from an Overcurrent Protection Component and Related Methods

An operation detection device for a overcurrent protection component, the overcurrent protection component having a closed state and an open state and outputting a transition event responsive to a transition between the closed state and the open state, the device comprising:

• a sensor electrically isolated from the overcurrent protection component and positioned in a location selected to allow the sensor to detect the transition event;
• and
• a switch circuit operatively coupled to the sensor that is configured to generate an output signal indicating a change in state of the overcurrent protection component responsive to detection of the transition event by the sensor.

A method of detecting an operation of an overcurrent protection component, the overcurrent protection component having a closed state and an open state and outputting a transition event responsive to a transition between the closed state and the open state, the method comprising:

• detecting the transition event using a sensor that is electrically isolated from the overcurrent protection component;
• and
• generating an output signal indicating a change in state of the overcurrent protection component responsive to detection of the transition event by the sensor.
