Fuse holders are typically made of conductive materials and are used to secure and connect fuses, providing circuit protection. They are characterized by high reliability, high precision, and low power consumption and are widely used in various electronic devices, such as home appliances, computers, and cars. Choosing the appropriate fuse holder can provide more reliable protection for different types of electronic devices, protecting circuits from issues such as abnormal currents and short circuits. Fuse holders come in different sizes depending on the size of the fuse, such as conventional, mini, and micro sizes.
