cylindriical fuse links and fuse holder

Q:Why the fuse resistance is large
A fuse is also known as a current fuse, and the IEC127 standard defines it as a "fuse-link". It is mainly due to overload protection.
Q:Fuses are generally not overloaded.
Our fuse in the actual work is used for short circuit protection.
Q:What does fuse insurance mean?
The role of the fuse is fixed pipe and external lead wire
Q:When selecting a fuse, you must consider several elements
The rated current of the fuse is confirmed at room temperature of 25 degrees, and the ambient temperature has a great impact on the rated current of the fuse. When the ambient temperature is higher than 25 degrees, the rated current value of the fuse will be attenuated, Below 25 degrees, the rated current value will be "added value"
Q:Why does the rated current of the fuse be based on the effective value as a standard?
The thermal effect of the conductor depends on the effective value of the current. So it is based on the effective value of the standard.
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:Why the neutral line can not fuse
if the zero line of the fuse accidentally damaged, in this circuit all with single-phase electrical equipment have 220V The ground voltage is quite dangerous.
Q:What is a semi-enclosed fuse
and is inserted into a porcelain box with a metal receptacle at both ends for use in low-pressure indoor use
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:The choice of fuse tube can be based on the following process
pulse (impact current, surge current, starting current and current transient value) on the life of the fuse tube
