Q:The choice of fuse tube can be based on the following process

pulse (impact current, surge current, starting current and current transient value) on the life of the fuse tube

Q:What is the common function of the circuit breaker and the fuse?

Fuse protection is to fuse, troubleshooting after the need to replace the melt to restore power supply, inconvenience

Q:Why can not the electric faucet be used to reset the fuse automatically?

in fact, this is the consumption Misleading and extremely irresponsible practices, it is ridiculous, but also very professional

Q:Fuse inspection check how to do?

fuse fuse signal is normal.

Q:What is the significance of the voltage on the fuse?

imilar to the neon bulb principle. Will make short circuit has a current through, to expand the fault. The The But also cause danger.

Q:The main parameters of the fuse selection

Usually in the DC circuit, using 10 times the rated current as the fault current, so that the fuse in a very short period of time off, through high-speed oscilloscope

Q:Selection of melt rated current

There are some equipment starting current is very large, but the start time is very short, so the protection of these devices to meet the needs of the equipment to meet the needs of the operation of the fuse required to start the motor does not fuse

Q:Fuse tube selection fuse factor

Ambient temperature or known operating temperature has a direct effect on the operation of the fuse. The higher the ambient temperature, the farther the fuse at work, the shorter the life expectancy.

Q:Is the home fuse fine fine or thick?

Rice cookers, cookers, water heaters that electricity is relatively large. Although it can not be used at the same time

Q:Why not tighten the fuse more easily blown

Normally, both ends of the fuse contact with the terminal, if the contact is good, the heat is better than the middle, should be the first part of the first fuse.
