2 RATINGS
GB/T 15166.2-2008 Chapter 4 apply. And supplemented as follows.
a) Rated voltage (see GB/T 15166.2-2008 4.1);
b) rated breaking capacity (see GB/T 15166.2-2008 and 5.1.2,5.1.3 4.7);
c) Rated Minimum breaking current.
In the system can not be sustained, low fault current (ie, current is greater than the rated current but less than the fuse rated minimum breaking current)
Case, it is possible to use the reserve of the fuse element as the only protection (instead of the common parts of the fuse, see
GB/T 15166.2-2008 of 9.3.4.3).
The case may arise sustained low current faults in the system and no associated switching means, you can make a backup of the fuse
Is damaged, you should use a common fuse fuse.
In the case (such as injection fuse or overload relay) with the exchange of high-voltage fuse fuse and other overcurrent protection device, requiring
Guaranteed minimum high voltage fuse breaking current is less than the corresponding pre-arcing time - current characteristics of the current value of the intersection.
In the case of high-voltage fuse combination striker has instantaneous tripping operation, it is necessary to ensure that the exchange of high-voltage fuse fuse
Less than the minimum breaking current fuse combination of electrical mechanical switching device maximum breaking current.
