In addition to configuring the circuit breaker that is created you can also customize the circuit breaker after it has been created but before it is returned to the caller. To do this you can use the addCircuitBreakerCustomizer method. This can be useful for adding event handlers to Resilience4J circuit breakers.

A circuit breaker is an electrical device that opens and closes a circuit by non-automatic means and automatically opens a circuit when a predetermined current overload is reached, without damage to itself. Circuit breakers protect circuits, and their function is similar to fuses.. A fuse is an electrical overcurrent protective device with a fusible portion that is …

The breakers cannot be set to an amperage other than what is available in the table above for breakers of that maximum trip unit rating. Values in the table above are the same values found on the breaker around the left knob, as ... or on as-designed parameters, and therefore should not be relied upon for any specific application and does not ...
