How does a circuit breaker protect a refrigerator?

A circuit breaker protects a refrigerator by interrupting the electrical flow in the event of an overload or short circuit, preventing potential damage to the appliance and reducing the risk of fire. When the refrigerator draws more current than the circuit can safely handle, the breaker trips, cutting off power to the unit. This safeguard helps maintain the integrity of the refrigerator's electrical components and ensures safe operation. By resetting the breaker once the issue is resolved, the refrigerator can resume normal functioning.
