1.Purpose:It offers reliable protection from low-level overloads that melt the fuse link, intermediate faults, and very high faults. It's commonly used in 10kV power distribution lines and transformers, serving as a short-circuit protection switch.
2.Works:It safeguards against overloads and faults by interrupting the electrical flow when excessive currents are detected. This device is commonly used on distribution lines and transformers to ensure reliable operation and prevent damage.
3.Features:
1)They are a combination of a fuse and a switch, specifically designed to protect electrical circuits by "dropping out" or disconnecting when excessive current flows through, which interrupts the circuit and prevents damage.
2)Unlike expulsion fuses that can be manually reclosed after operation, drop-out fuses are not reclosable and need to be replaced once they operate. They are particularly useful in protecting distribution transformers from current surges and overloads.
