    Many low voltage circuits have fuses to protect the circuit from overloads. In answer to your question: It's the amperage that determines the type of fuse. A low voltage circuit with high amperage could use one, like on a ship. Small fuses to protect 24 volt control circuits in AC and heating units only need about a 1-2 amp fuse.
