A fuse holder is a device that securely holds a fuse in an electrical circuit. It ensures that the fuse can be easily replaced when it blows, protecting the circuit from overloads or short circuits. Fuse holders come in various designs, including inline and panel-mounted types, and are used in many applications, from household appliances to automotive systems. These holders are typically made of durable materials that can withstand heat and electrical stress. They are essential for maintaining safety in electrical systems, as they allow for quick access to the fuse, ensuring that the circuit can be restored to normal operation without delay.
