Either circuit breakers or fuses can be used as the overcurrent protection for a VFD.
Fuses are less likely to have nuisance outages than circuit breakers and are a better option for circuits that have a high-fault current.
However, fuses can drop out one leg of a three-phase circuit and cause damage to a motor if not properly equipped with phase-loss detection.
Circuit breakers can easily be reset if tripped and do not require spares to be stored, which can be costly.
