1.Bussmann IEC Standard Fuses (Compliant with IEC60269, DIN/VDE, CE Certified | 4 Main Product Lines + Quick Selection Guide)
Applicable Standards: IEC60269-1/2, VDE0636, DIN43620; Standard rated voltage: 690VAC, breaking capacity: 80~120kA.
Application categories: gG full-range cable protection, aM partial short-circuit protection for motors, aR ultra-fast semiconductor fuses, gPV dedicated PV fuses.
2.Cylindrical Cartridge Fuses (With CH DIN Rail Holders, Widely Used for Low-current Control & Distribution).
3.NH Blade Fuses (Main circuit for industrial distribution cabinets, size 000 ~ 4, 2~1250A)
Part number rule: Ampere + NHG/M + Size + B-690
NHG = gG full protection (cable & distribution); NHM = aM motor exclusive; 690 = 690VAC, 120kA breaking capacity
Available sizes: NH000, NH00, NH1, NH2, NH3, NH4.
4.aR Ultra-fast Semiconductor Fuses (For Inverters, Rectifiers & Converters, IEC+BS Standard Approved)
FEE/EET/LET series, 690VAC/500VDC, 200kA breaking capacity, aR ultra-fast performance for IGBT & thyristor protection.
Popular items: 32FEE, 63EET, 100FEE (DC side of frequency inverters).
5.Quick Application Selection (Cross-reference with UL Class North American Fuses)
PLC / small transformer / control circuit→C10/C14 gG (equivalent to UL Class CC)
Fan, air compressor, 3-phase motor→C-series aM / NHM blade fuse (equivalent to UL Class J/RK5)
Inverter & power semiconductor→FEE/EET aR ultra-fast fuse (equivalent to UL Class T)
Main incoming feeder of distribution cabinet→NHG00~NH3 gG blade fuse (equivalent to UL Class L)
PV combiner box→gPV DC fuse.
