Fuses are important electronic protection components used to safeguard circuits and equipment from overcurrent and short-circuit conditions. They operate by breaking the circuit when the current exceeds a safe limit, preventing damage to sensitive components and reducing the risk of fire or equipment failure. Fuses are commonly used in power supplies, control circuits, and electrical distribution systems to ensure safe operation. Available in various types such as cartridge fuses, blade fuses, glass fuses, ceramic fuses, and resettable fuses, they come with different current ratings, voltage ratings, and response characteristics. Fuses are widely used in consumer electronics, industrial equipment, automotive systems, and power systems, contributing to enhanced safety, reliability, and circuit protection.
