Current-limiting fuse / cylindrical / high-voltage / HRC

H.R.C. fuses are normally used to protect
small banks and/or three-phase capacitors, designed
in accordance with DIN and IEC standards for protection
against thermal and dynamic effects, caused by short
circuit current exceeding the tolerated value in magnitu-
de and duration.
The main characteristics ofH.R. C. fuses are:
• low minimum trip current;
• low dissipated power;
• low voltage of the electric arc;
• high breaking capacity;
• high current limiting;
• easy maintenance;
• small dimensions.
H.R.C. fuses are the best solution in situations where
using other protection systems would require an excessi-
ve cost compared to that of the whole system.
To obtain the maximum current limitation, and
therefore the best protection, the rated current of the
chosen fuse must be selected at the lowest possible level
compared to the value of the current equal to about 2
times In.
The fuse cartridge striker, besides performing the
function of signalling tripping, can be associated with
the device for turning off the operating-disconnecting
switch and/or with the external indicator device.
Besides H.R. C. fuses, accessories can be supplied such
as the specific fuse holder bases and the trip signalling
devices.
