- Q: What does the fuse HRC say?
- It limits the fusing time at the rated voltage to be equal to or less than the first main wave or symmetrical current wave period,
- Q: What is the principle of choosing a fuse?
- of the protective object to provide reliable protection over the entire curve.
- Q: Fuse F5AL250V said what
- Fuse: fuse (fuse) is also known as the current fuse, IEC127 standard it is defined as "fuse (fuse-link)"
- Q: When the melt is blown, what are the possible reasons
- short circuit fault or overload operation and normal blow
- 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: What is the fuse often used?
- the second part of the electrode, usually two, it is an important part of the melt and circuit connection, it must have Good conductivity, should not produce a significant installation of contact resistance
- Q: What is the significance of the voltage on the fuse?
- Fuse pressure value is the fuse in the fuse can be a reliable cut off the current, such as the use of the voltage is too high, will have been broken or broken fuse and fuse shell (metal part) pull the arc discharge
- Q: Why is the fuse broken
- There is a short circuit in the circuit, resulting in short circuit current, short circuit current is too large fuse fuse
- Q: Is the fuse the capacitor
- When the line occurs short circuit or overload, the heat generated by the high current flowing through the self-recovery fuse causes the polymer resin to melt and the volume grows rapidly to form a high resistance state (b), and the working current is rapidly reduced to limit and protect the circuit.
- Q: Fuses can be divided into high-voltage fuses and low-voltage fuses.
- the protection of the voltage transformer fuse, the protection of the power capacitor fuses, protect the semiconductor components of the fuse,
