Fuses are protective devices used to prevent excessive current from flowing through a circuit, protecting sensitive components from damage due to overloads or short circuits. When the current exceeds a predetermined limit, the fuse blows, interrupting the flow and preventing further damage. Fuses are essential for ensuring safety in power supplies, automotive systems, and industrial equipment.

With their simple yet effective design, fuses provide reliable protection for both low- and high-voltage circuits. For engineers working on power-sensitive projects, fuses are a critical component for safeguarding electronic systems against potential faults.
