What is the purpose of a circuit breaker in a ship electrical distribution system?

The purpose of a circuit breaker in a ship’s electrical distribution system is to interrupt current when something goes wrong—such as an overload or a fault—so equipment and personnel stay protected. When a circuit draws more current than it should or a short occurs, the breaker trips and opens the connection, stopping the flow of electricity to prevent damage, overheating, or fire. After the fault is cleared, the breaker can be reset to restore power. It’s not meant to block all current at all times, and it doesn’t convert AC to DC or store energy—that’s handled by other devices like rectifiers and energy storage equipment.
