This is necessary because a fuse is a protection against an overcurrent; excessive current produce melting.

Soft low melting solid which is a good conductor of heat?

The metal lead. Solid at room temps, low melting point, good conductor of heat and electricity.


What metal has a low melting point that is used in circuits?

Gallium is a metal with a low melting point of about 29.76°C (85.57°F) and is often used in electronic circuits. Its ability to remain liquid at relatively low temperatures makes it useful for certain applications, including in semiconductors and as a component in various alloys. Additionally, gallium's unique properties allow it to be used in some high-performance electronic devices.

Is gold used in circuit breakers?

Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.


Can anyone explain the M effect of HBC or HRC fuses?

M effect stands for 'Metcalf' effect after the person who discovered it. It involves the use of a small amount of low-melting point alloy (often solder) fixed to the fuse element (wire or strip). Under low overload conditions the fuse element heats up causing the M-effect alloy to diffuse into the metal of the element, increasing its resistance and hence shortening the time to blow compared to the same element without M-effect. Under high overload conditions the fuse element heats up so quickly that there is no time for diffusion to occur. Surprisingly, fuse designers use this effect as a way of creating a fuse with time-delaycharacteristic, because it allows them to use a thicker wire (or strip) than they would otherwise be able to for a given current rating. It is this thicker material that allows a time-delay fuse to withstand short-duration high- current surges.

Is fuse wire characterized by high resistance and high melting point?

No, fuse wire is characterized by low resistance and a low melting point. This allows the fuse wire to melt quickly and break the circuit when there is an overload of current, thereby protecting the circuit from damage.

What is inside a fuse?

There's a thin metal wire with a low melting point inside a fuse.It may be a nichrome wire.However copper wire is not suitable to be the thin wire inside a fuse cause it has a very high melting point.


Naphthalene has high or low melting point?

Naphthalene has a relatively low melting point of around 80 degrees Celsius.


Does the material used for a fuse wire need to have a low or a high melting point - a low or high ductility - a low or high resistivity?

The material for the fuse wire should have low resistance and a low melting point. Ductility is a incidental factor. As the current flow nears the fuse rating, the high current flow causes the wire to heat up quickly. It then melts, opening (breaking) the circuit. This is how the fuse limits the amount of current that can flow through a circuit.
