A circuit breaker with at least one disconnect mechanism and a smart monitoring system implements nuanced fault logic in order to minimize disruption to operation of the circuit breaker under a fault condition, and enables the circuit breaker to address nuisance or low severity faults separately from load switching. Under low severity or nuisance fault conditions, the smart monitoring system temporarily disconnects affected loads from the power supply rather than tripping the entire circuit breaker so that the loads can be reconnected to the power supply if the fault condition resolves within a short amount of time. In addition, the disconnect mechanism(s) that are used to temporarily disconnect the load(s) are configured to be re-closed after opening without requiring manual intervention. In high severity fault conditions, the smart monitoring system actuates tripping of the entire breaker, requiring manual re-closing of the circuit breaker.

Fault logic based operating system for one or more disconnects in a circuit breaker, with provision of limited automatic self-reset and/or reset by software application

A system includes a circuit breaker and an adapter. The circuit breaker includes a front face with a light source on the front face. The adapter is configured to be releasably held on the front face in an installed position. The adapter includes a light sensor that aligns with the light source in the installed position. The light source and the light sensor are configured to communicate such that the adapter receives operational data from the circuit breaker in the installed position.

Adapters for obtaining operational data from circuit breakers and related systems and methods

A method for obtaining operational data from a circuit breaker includes: releasably attaching an adapter to a circuit breaker; actuating a test button on the circuit breaker using the adapter; moving a handle of the circuit breaker to an on position; initiating output of a light signal from the circuit breaker that is representative of operational data of the circuit breaker in response to the actuating and moving steps; and receiving the light signal at the adapter.
