Q:What is the factor of the fuse tube?

When the flow through the fuse is quite large or even short circuit, still require the fuse can safely break the circuit, and does not bring any destructive

Q:Socket and fuse are connected to the zero line or FireWire

The socket is a device that can be connected to the power line in parallel with the appliance. Therefore, the terminals on the socket will have a firewire (L) and a neutral line (N),

Q:How do the use of circuit breakers in the end?

the current is too large when the expansion coefficient of the first expansion, play a role in cutting off the powe

Q:Fuses are generally not overloaded.

No limit measures can be taken after the load current has increased.

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

The trip speed of the circuit breaker is in milliseconds (ms), relatively slow, and some occasions where the cut speed is high is not applicable

Q:How does the fuse be classified

According to the fuse speed points, can be divided into: special slow fuse (generally used TT), slow fuses (generally used T), medium-speed fuses (generally used M), fast fuses (generally F ), Special fast fuses (generally indicated by FF).

Q:The difference between DC fuses and AC fuses

Alternating current is a sinusoidal waveform alternating conduction, the weekly wave has a zero, then the minimum value of electricity is very easy to extinguish the arc

Q:Fuses should be repaired with the power distribution unit at the same time:

check the fuse, the melt and the protected circuit or equipment is matched, if any problems should be investigated.

Q:What are the fuse, automatic repair fuse what principle

According to the protection of the form, can be divided into: over-current protection and overheating protection

Q:Are there any resistance to the fuse?

The fuse has a resistance value, in fact, even the wire also has resistance, but the resistance of the wire is very small (the nature of the conductor), in the general circuit calculation, we usually do not count
