Fuses are used as safety devices.
Fuses ensure that excessive current does not flow in the electric circuit. If excessive current flows in the electric circuit it may cause damage to the electric appliances.
There is a maximum limit on the current which can safely flow through a circuit. If by accident the current exceeds this safe limit, the wires may become overheated and may cause fire.
