The frequency converter provides fullshort circuit protection in case of a short-circuit on themotor.Overcurrent protection:Provide overload protection to avoid overheating of thecables in the installation. Overcurrent protection mustalways be carried out according to national regulations.Fuses must be designed for protection in a circuit capable ofsupplying a maximum of 100,000Arms (symmetrical), 480Vmaximum.Non UL compliance:If UL/cUL is not to be complied with, Danfoss recommendsusing the fuses mentioned in the below table, which willensure compliance with IEC61800-5-1:In case of malfunction, not following the fuse recommen-dation may result in damage to the frequency converter.UL NonULBussmann Bussmann Bussmann Bussmann Max.FusePowerkWType RK5 Type RK1 Type J Type T TypegG3 x 200-240V0.25 FRS-R-10 KTN-R10 JKS-10 JJN-10 100.37 FRS-R-10 KTN-R10 JKS-10 JJN-10 100.75 FRS-R-10 KTN-R10 JKS-10 JJN-10 101.5 FRS-R-10 KTN-R10 JKS-10 JJN-10 102.2 FRS-R-15 KTN-R15 JKS-15 JJN-15 163.7 FRS-R-25 KTN-R25 JKS-25 JJN-25 255.5 FRS-R-50 KTN-R50 JKS-50 JJN-50 507.5 FRS-R-50 KTN-R50 JKS-50 JJN-50 5011 FRS-R-80 KTN-R80 JKS-80 JJN-80 653 x 380-480V0.37 FRS-R-10 KTS-R10 JKS-10 JJS-10 100.75 FRS-R-10 KTS-R10 JKS-10 JJS-10 101.5 FRS-R-10 KTS-R10 JKS-10 JJS-10 102.2 FRS-R-15 KTS-R15 JKS-15 JJS-15 153 FRS-R-15 KTS-R15 JKS-15 JJS-15 154 FRS-R-15 KTS-R15 JKS-15 JJS-15 155.5 FRS-R-25 KTS-R25 JKS-25 JJS-25 257.5 FRS-R-25 KTS-R25 JKS-25 JJS-25 2511 FRS-R-50 KTS-R50 JKS-50 JJS-50 5015 FRS-R-50 KTS-R50 JKS-50 JJS-50 5018.5 FRS-R-80 KTS-R80 JKS-80 JJS-80 6522 FRS-R-80 KTS-R80 JKS-80 JJS-80 6530 FRS-R-80 KTS-R80 JKS-R80 JJS-R80 8037 FRS-R-100 KTS-R100 JKS-R100 JJS-R100 10045 FRS-R-125 KTS-R125 JKS-R125 JJS-R125 12555 FRS-R-150 KTS-R150 JKS-R150 JJS-R150 15075 FRS-R-200 KTS-R200 JKS-R200 JJS-R200 20090 FRS-R-250 KTS-R250 JKS-R250 JJS-R250 250Quick Guide VLT HVAC Basic Drive FC 101 Quick Guide6 MG.18.A1.02 - VLT® is a registered Danfoss trademark11
