High Voltage Limiting Fuses
The high-voltage fuse cartridges shown here are current limiting ones.
They are made according the following standards: EN60282-1, IEC 282-1, DIN 43.625 and NF-C 64-200.
Making of the fuse cartridges is made of two different ways, both of them indelibles, which are:
a) By engraving over one of the metallic caps, we can obtain the following values: rated voltage, rated current and manufacture date.
b) In an adhesive label, over the insulator, it will be given the following values, using a numerical system and a bar code: trade mark, type, manufacture standards, rated voltage, rated current, minimum breaking current, breaking capacity, cold resistance and identification information.
Fuses CEI 828-1 DIN 43.625
IB-D1 e IB-D2 f uses are manufactured according to the standards UNE-EN 60282-1, DIN 43.625 and
IEC 282-1 standards.
At the moment, DIN system form dimensions is standardized in many European countries and
gives a single 45mm contact diameter for all ratings.
These low losses fuse are hermetically sealed and can be used in indoor and outdoor conditions and also in SF metal switch-gear; they are supplied for each voltage in two different insulator diameters, depending on the rated current.
They are provided of a tripping device that can withstand a power of 4 daN, in a course of 20mm.
