Small motor thermal overload protection
WebThese overcurrent devices (fuses or circuit breakers) protect the conductors feeding the motor from overcurrents caused by short-circuit or ground-faults. They are not designed to protect the motor windings. The motor branch circuit conductors are protected from overload conditions by the motor overload protection specified in Section 430-32.
