High voltage fuse short circuit protection function
High-voltage fuses provide short-circuit protection. When a circuit or a device within it is overloaded or malfunctions, and the current in the circuit exceeds a specified value after a certain period of time, the fuse element heats up and melts, thereby disconnecting the circuit and interrupting the current, protecting the circuit or device.
