Fuses are rated according to the maximum current that they can safely interrupt. The rating is usually expressed in amperes (A) or watts (W). For example a common household fuse is rated at 15 A or 1500 W. This means that the fuse can safely interrupt a current up to 15 A or 1500 W without blowing.
The rating of a fuse is determined by the amount of current that it can carry without overheating and melting. The higher the rating the higher the current that the fuse can handle.
Fuses are made from a variety of materials including metals glass and ceramics. The choice of material depends on the application and the desired properties of the fuse. For example metal-oxide fuses are used in high-current applications because they have a low melting point and a high resistance to current.
Fuses are typically rated according to their maximum current interruption capability. The most common ratings are in amperes or watts. For example a common household fuse is rated at 15 A or 1500 W.
When choosing a fuse it is important to select one with a rating that is appropriate for the application. If the fuse is rated too low it may not be able to safely interrupt the current in the event of a fault. If the fuse is rated too high it may not blow in the event of a fault which could lead to catastrophic damage.
How are fuses rated?
Answer: Fuses are rated by their amperage and voltage.
