Product dedicated to photovoltaic installations Operating ranges adapted to low overcurrents specific to photovoltaic systems. High reliability Absolute protection over time guaranteed by the simplicity of manufacture and function (Joule effect). No downgrading of fuse characteristics over time. Improved safety The energy released whilst eliminating the fault (fuse blowing) is contained within the cartridge (no degassing). > Associated range of switches and fuse bases, dedicated combs and connection accessories Compliance with standards > IEC 602696 > IEC 60269 > IEC 602692 What you need to know Characteristics used I SC : short circuit current of the string. I SC MAX: short circuit current of the string related to maximum sunlight density. I RM : maximum admitted reverse current. I n : fuse rating or fuse rated current (at 25 C in a RM fuse base). N c : number of strings in parallel. U e : fuse maximum operating voltage. U OC MAX: maximum open circuit voltage in the lowest temperature conditions. When to protect A PV string requires an overcurrent protection when its own maximum admissible reverse current characteristic (Irm) is less than the current generated by the rest of the installation (current generated by the other "Nc" strings). How to protect Protection against overcurrents has to be applied to both polarities, regardless of wheather the DC installation is earthed or not. 368 General Catalogue 207208
from to 600 A, up to 500 VDC How to choose the right fuse protection Voltage U e > U OC MAX In the absence of complementary information use U OC MAX =.2 U OC Fuse rating determination Determination of the fuse rated current consists of choosing a protection capable of: Supporting without fusing the normal overload current during the periods of maximum sunlight density at the ambient temperature of the enclosure in which the fuse is installed, I n > I SC MAX In the absence of complementary information use ISC MAX =.4 I SC Melting and reliably clearing the fault before the PV modules are damaged by the reverse current.
