Q:Fuse is an overcurrent protection appliance.

When used, the fuse is connected in series to the protected circuit. When the current of the protected circuit exceeds the specified value, and after a certain period of time

Q:The difference between the fuse and the air switch

fast fuse is mainly when there is short-circuit over-current, over-voltage can be timely blow to protect the load and line normal to prevent accidents, failure to expand.

Q:How to read the fuse ring

four color ring followed by: red, red, yellow, gold. The first color ring red for 2, the second color ring red 2, are valid numbers, the third color ring yellow is 4, said the effective number after 4 "0", the fourth ring is golden, that the error is 5%

Q:Fuses are generally not overloaded.

Overload protection: generally refers to the increase in load current can take measures to limit the protection of equipment.

Q:Is the fuse blown depending on the size of the current flowing through it?

In the design of special certification and export equipment, be sure to

Q:What is a quick fuse:

Fast fuses are mainly used for short circuit protection of semiconductor rectifier or rectifier devices

Q:Use a multimeter to check if the fuse is damaged

110KW motor, must be a step-down start, so choose the low value of the rated current of 2 times.

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?

The fuse has a resistance value, in fact, even the wire also has resistance, but the resistance of the wire is very small (the nature of the conductor), in the general circuit calculation, we usually do not count

Q:The fuse is to prevent the circuit

the circuit will produce a lot of current through the fuse, the fuse will heat cut off the power to achieve the role of protection circuit to prevent the circuit
