Q: The main parameters of the fuse selection: The fuse must be able to break the fault circuit without breaking the surrounding circuit.

Q: Why the neutral line can not fuse: In the industrial electricity (380V), three-phase air switch (than the anti-over-current role of the fuse, but also more)

Q: What does fuse insurance mean?: When the fuse is connected to the circuit, the melt is connected in series to the circuit, and the load current flows through the melt.

Q: How do I use a multimeter to detect if the fuse is broken: if the pile under the detection of no voltage, you can conclude that the fuse burned.

Q: Why the resistance of the fuse to be large: The size of the current and the resistance determines the rate at which the heat is generated. The structure of the fuse and the condition of its installation determine the rate of heat dissipation. If the velocity of heat is less than the rate of heat dissipation, the fuse will not blow

Q: Quickly disconnect the fuse and cut off the fuse slowly: the other hand, the use of slow blow fuse where the use of fast-blow fuse , It will often cause the boot that fuse can not work properly.

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
