fuses are used in electrical circuits. these users protect the electrical devices from getting damaged. in case of short circuit excessive current flows through the circuit and if these can reach the device the device will get damage but fuses protect the device.
What type of safety devices are used in electric circuits Class 10?
Fuse wire is a safety device which is used to limit the current in an electrical circuit.

What are the requirements of safety devices in electric system?
The fuse interrupts the connected circuit and absorbs the electrical overflow to protect electrical equipment from extensive damage caused by fire or overheating. Fuses, among other overcurrent protection devices, are required in electrical systems to protect human life and to avoid property damage.
What are some electrical safety features?
Because electricity can be so dangerous, safety features are built into modern electric circuits and devices. They include three-prong plugs, circuit breakers, and GFCI outlets . You can read about these three safety features in the Figure below.

How does a safety fuse works?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow . This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.
How does a safety device function?
Safety devices are equipped with functions such as a direct opening action for switches and a forcibly guided mechanism for relays , as required by standards. These functions are designed to operate correctly within the control system in which they are used.
