A fuse cuts off the electricity supply in a circuit when something goes wrong. Inside the fuse is a thin wire, able to carry a safe amount of current but no more. If an electrical appliance overheats it will start to use more electricity. The thin wire in the fuse (usually in the plug) heats up and melts. This breaks the circuit and cuts off the electricity.
