What is the important of fuse?

A fuse(s) is needed in any electrical system (AC or DC). These protection devices react to the amount of heat being produced by electricity passing through wires and/or components. They are used so as to protect wires and components from the extreme heat produced should there be an electrical overload or short circuit.

What is Kit Kat fuse?

⭕️Kit Kat fuse is a semi conductor fuse enclosed fuse for Domestical Uses. ⭕ fuse wire is not kept open in the air and it is also not completely closed . ⭕️The fuse wire is attached to fuse which can be removed or connected to fuse base.

How do I choose a fuse?

Fuse selection process

1. Make sure to select a fuse that has a rated voltage higher than the voltage of the circuit.
2. Only select DC rated fuses for DC circuits, and AC rated fuses for AC circuits.
3. When selecting fuses, please confirm that the fuse you have selected can safety clear abnormal currents in the equipment in which it is to be used.

How do fuse work?

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.

What is a fuse wire?

Answer: A fuse wire is a safety wire connected in series with the live wire, in case of any large current supply or malfunctioning in the electric connections it melts and breaks the electric circuit. Characteristics: High resistivity. Low melting point.

What are the values of fuse wire available?

Answer. The safe value of fuse means the maximum current that the fuse can withstand. Like for example if the safe value of fuse is 5A, then that particular fuse will not allow a current higher than 5A to pass through circuit. If the current exceeds , the fuse wire will melt and the circuit will be disconnected .

What is a fuse what material is used for make fuse wire?

Solution: Fuse wire is made of alloy of lead and tin having low melting point of 200°C.

What is used in fuse?

The material used for making fuse element has a low melting point such as tin, lead, or zinc. A low melting point is, however, available with a high specific resistance metal shown in the table below. The material mainly used for fuse element are tin, lead, silver, copper, zinc, aluminum, and an alloy of lead and tin.

How is MCB better than fuse?

MCBs are more sensitive to current than fuses. They immediately detect any abnormality and switch off the electrical circuit automatically. This prevents any permanent damage to electrical appliances and human beings. The MCB detects any excess current and breaks the circuit.

What is the fuse wire normally made up of and why?

Generally an alloy of tin and lead is used as the material of the fuse wire as it has high resistivity and low melting point. Usually the fuse wire is a thin wire to be the resistance of the fuse wire is much more than that of the live wire. list of width of wire and current carrying capacity for fuse wires.
