Abstract
A method of establishing, and recording, the cause of a power interruption to the load in solenoid-operated electronic miniature circuit breakers of various types without extensive digital resources is presented. In some designs of electronic miniature circuit breakers a circuit breaker trip event will change the inductance of the trip solenoid. This change will take place for an electronic trip or a mechanical trip. A record of the electronic trip signal issued to the solenoid will be present to check against and differentiate the occurrence of an electronic trip from a mechanical trip. The mechanical trip occurs without the electronics and is also indicated by the change in inductance. Thereby, the cause of the power interruption can be determined, recorded and reported.
