Q:What is the difference between fuses and fuses?
Made a plug-in shape of a component, its internal core is the fuse.
Q:The difference between the fuse and the air switch
The air switch is normally used for the opening and closing of the main power supply, and the quick fuse is used for the protection of a single electrical equipment
Q:Fuse fuse all the reasons
Fuse blown the essence: the current flows through the fuse heat, so that the fuse heat, if the heat can not be dispersed in time, the fuse continues to heat up to melt melting after the break.
Q:Is the fuse blown directly with copper wire?
But if the lead with the fuse, its melting point is low, when the current is too large when the fuse, you can protect the electrical.
Q:Why is there a diode icon on the fuse?
Parallel to the fuse at both ends of the light-emitting diode does not light, when the fuse is blown,
Q:Fuse always burn ! Is the line short circuit yet?
if the use of any of these appliances alone, it will burn insurance, that may be the electrical failure, it was caused by the professional electrical repair division to check the electrical friends
Q:What is the role of thermal fuse
When the motor and other load equipment beyond its rated temperature value to play an instantaneous power protection role
Q:Why not tighten the fuse more easily blown
Not tight or lead wire angle is too small, making the fuse and copper terminals between the contact area is not big enough, contact resistance, heat, easy to melt contact.
Q:What does the fuse HRC say?
Current limiting fuses are divided into resistive current limiting and arc reactance conversion current limiting
Q:What are the hidden faults of the automatic reset fuse?
Can automatically reset the fuse, in fact, before N years already have, but applied in other areas, and now the field of electric faucet has emerged some unprofessional manufacturers claim to use the domestic first fuse automatic reset technology
