What does a fuse holder do in a circuit?

A fuse holder is a device that securely holds a fuse within an electrical circuit, providing a point of connection for the fuse to interrupt the circuit when necessary. Its primary function is to protect the circuit from overloads or short circuits by breaking the connection if the current exceeds a safe level, thus preventing damage to components and reducing fire risk. Fuse holders can be found in various forms, including panel-mounted or inline types, making it easier to replace fuses when they blow.
