Q: What is the principle of choosing a fuse?
The protection characteristics of the fuse must be well matched with the overload characteristics
Q: What is the working principle of the fuse
so that the principle of breaking the circuit made of a current protector.
Q: How do I use a multimeter to detect if the fuse is broken
respectively, which fuse is detected to burn, when the multimeter reaction resistance is good Of the resistance is the loss of the fuse is burned
Q: What is a spiral fuse:
Spiral Fuse. Breaking current is large, can be used for voltage level 500V and below,
Q: What is the factor of the fuse tube?
Structural features and installation form
Q: What is the role of thermal fuse
When the metal sheet after overheating occurs, the contact is disengaged and the circuit is disconnected. After the temperature is reduced, the metal sheet is restored and the circuit is combined.
Q: Is the fuse blown depending on the size of the current flowing through it?
The rated voltage of the fuse is raised from the safe use of the fuse, which is the highest operating voltage of the circuit in which the fuse is in safe working condition.
Q: Fuse tube selection fuse factor
When the fuse is energized, the voltage at both ends is much less than the rated voltage, so the additional load is not critical
Q: What is the self-recovery fuse:
The use of metal sodium as a melt, at room temperature with high conductivity.
Q: The difference between DC fuses and AC fuses
any waveform of DC does not exist in the zero, in the open DC short-circuit fault current
