Q:According to the breaking speed, can be divided into

Special fast fuse (generally indicated by FF)

Q:What are the precautions for using the fuse?

fuse protection characteristics should be protected with the overload characteristics of the object, taking into account the possible short-circuit current, the choice of the corresponding breaking capacity of the fuse.

Q:Why can not the neutral line fuse

And when the zero line fuse blown after the shell is only in the ground insulation is not good

Q:What are the characteristics of the fuse?

The rated current of the melt is selected according to the load current of the protected equipment

Q:What material is used for the fuse

Fuse material is mainly made of low-melting alloy such as aluminum antimony alloy.

Q:Fast break fuse and slow cut fuse difference

in addition to protecting the IC circuit, the majority of the use of fast-fuse fuse can be used to slow-blow fuse to improve the anti-jamming capability

Q:What is a semi-enclosed fuse

The semi-enclosed fuse is mounted on a porcelain frame

Q:Fuse always burn Is the line short circuit yet?

the insurance has not been burned, indicating that all electrical work is normal no problem, while the use of electrical insurance It will burn, indicating that beyond the load, you can properly replace the fuse.

Q:Is the home fuse fine fine or thick?

I suggest you use a 30A air switch, this can reduce a lot of trouble The

Q:Are there any resistance to the fuse?

In general, when the circuit current or voltage exceeds the rated value, the fuse will not immediately fuse
