Frequently Asked Questions:
Q. How is a fuse rated?
A. Fuses are rated based on their current-carrying capacity and voltage rating. The current rating specifies the maximum safe current the fuse can handle without melting, while the voltage rating indicates the maximum voltage the fuse can safely interrupt.
Q. What is the difference between fast-blow and slow-blow fuses?
A. Fast-blow fuses quickly melt when exposed to excessive current, providing rapid protection. Slow-blow fuses, also known as time-delay fuses, have a delay before melting, allowing temporary overcurrents (such as motor startup) to pass without tripping the fuse.
Q. Can a blown fuse be reused?
A. No, a blown fuse should be replaced with a new one. Once a fuse has melted and interrupted the circuit, it cannot be reset or reused.
