In most cases the switch disconnect will do the job. It depends on the circuit wiring that the fan is connected to. If the circuit is a three wire circuit you could receive a shock when you open the neutral wire if you accidentally touch the neutral and the system ground at the same time. As an electrician we always take the safer road and disconnect the power supply from the load at the breaker and not depend on the switch for complete circuit isolation.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.

A 300 watt bulb requires a circuit breaker of at least 2.5 amps. This can be determined by dividing the power (300 watts) by the voltage (120 volts). However, considering normal breaker sizes, a 5 amp breaker would be sufficient for a 300 watt bulb.
Your ceiling fan may not be turning on due to a faulty switch, a blown fuse, a tripped circuit breaker, or a problem with the fan motor. Check these components to troubleshoot the issue.
