Fuses are rated with specific values to indicate the maximum current they can safely handle. These ratings (1 A, 2 A, 3 A, etc.) help in selecting an appropriate fuse for a specific circuit or device, ensuring protection without unnecessary interruptions.

Fuses are rated with specific values such as 1 A, 2 A, 3 A, 5 A, and 10 A to protect electrical circuits from excessive current. The rating indicates the maximum current the fuse can safely handle without breaking or “blowing.” When the current exceeds the rated value, the fuse heats up and melts, breaking the circuit and preventing damage to connected devices or components. The specific ratings are chosen based on the normal operating current of the circuit and the need to disconnect the circuit if a fault or overload occurs. Selecting the appropriate fuse rating is crucial for ensuring effective protection and preventing potential hazards in electrical systems.
