Q:What is the factor of the fuse tube?

Safety certification of fuses and their requirements

Q:Why can not change the fuse when replacing the fuse

Change the crude after the fuse does not work, the current is too large, it will burn out the meter

Q:What is the installation of the fuse.

The current and duration of the fuse pipe must be cut off (this condition is determined by the designer's protection requirements for the particular circuit).

Q:When replacing the melt, it is required to

Before installing the new melt, find out the cause of the melt fuse, not determine the cause of the fuse, do not replace the melt test.

Q:Fuse according to the breaking current range can be divided into several

This fuse is mainly used to protect power transformers and general electrical equipment.

Q:What are the hidden faults of the automatic reset fuse?

Fuse is a very important part of the electric faucet product, the line is called "overheating protection", mainly from the role of over-temperature and anti-dry protection, when the machine temperature occurs when the automatic fuse off the power supply to protect the consumer And property security.

Q:If it is possible, is it possible to have an electric shock?

The line is too long and the wire Too thin, then there will be a pressure drop! There is the use of this line is too high! I use the voltage meter to find the voltage when the voltage is 170V

Q:What is an open fuse

Breaking the current in the atmosphere to produce a larger sound and light.

Q:Why not tighten the fuse more easily blown

Not tight or lead wire angle is too small, making the fuse and copper terminals between the contact area is not big enough, contact resistance, heat, easy to melt contact.

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
