Q:Is the fuse the same as the fuse?
Fuses by the various departments of experts and professors through research and development of a new type of high breaking capacity fuse or high pressure fuse equipment.
Q:The difference between the fuse and the air switch
fast fuse is mainly when there is short-circuit over-current, over-voltage can be timely blow to protect the load and line normal to prevent accidents, failure to expand.
Q:Broken speed, which can be divided into?
Japanese regulatory fuse (PSE).
Q:Selection of melt rated current
Because a variety of electrical equipment has a certain overload capacity, allowing a long time under certain conditions to run;
Q:Why the neutral line can not fuse
In the electricity (220V) from the theory and practice, the installation of fuses on the zero line is not allowed,
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 air switch is different from the fuse
the air circuit breaker fast tripping over-current is generally 10 times, with anti-time characteristics, over-current multiples, action delay is long, do not have a small multiple over-current quick-break protection
Q:What are the fuse, automatic repair fuse what principle
Fuses for overtemperature protection are commonly referred to as temperature fuses.
Q:Fast break fuse and slow cut fuse difference
Slow-breaking fuses also have short-circuit and overload protection functions
Q:The choice of fuse tube can be based on the following process
the ambient temperature on the impact of the carrying capacity of the fuse tube, see "ambient temperature".
