Q:Fast break fuse and slow cut fuse difference
Slow-breaking fuses also have short-circuit and overload protection functions
Q:What are the precautions for using the fuse?
fuse melt according to the requirements of the use of matching melt, not allowed to arbitrarily increase the melt or use other conductors instead of the melt
Q:Why can not the neutral line fuse
In the electrical safety work specification only provisions of the zero line is not allowed to install insurance,
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:Is the fuse the capacitor
When the fault is removed, the self-recovery fuse recovers the crystal, the volume shrinks, the conductive particles re-form the conductive path, and the self-healing fuse returns to the low resistance state, thus completing the protection of the circuit without manual replacement.
Q:Fuse F5AL250V said what
If the circuit is properly placed in the fuse, then the fuse will rise in the current to a certain height and heat,
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:Where the induction cooker fuse is located
there are machines in the 220V voltage before the rectifier bridge, there is a varistor (overvoltage protection, also Called chopper
Q:When the melt is blown, what are the possible reasons
the use of the melt too long, the melt due to oxidation or high temperature during operation, so that the characteristics of the melt and make mistakes.
Q:How to classify fuses
According to the volume points, can be divided into: large, medium, small and micro.
