Brick-Type Fast-Acting 60 A to 100 A Fuses - 1245HC Series

Eaton's Bussmann series 1245HC fuses are fast-acting fuses for high-power, ultra high-current carrying capability in a compact surface-mount package. The 1245HC has a 1245 EIA footprint and is available with a nominal current rating up to 100 A, providing reliable circuit protection in high-current applications. This brick fuse can replace larger cartridge fuses or eliminate the need to parallel lower nominal current rated alternatives rated for up to 125 V_AC and 72 V_DC and can interrupt up to 500 A and 1000 A at their respective AC and DC rated voltages. With low DCR for higher power efficiency, lower power loss, and less self-heating, the 1245HC shares the same footprint as Eaton's 1025HC 40 A and 50 A fuses, providing designers a single fuse footprint for nominal current ratings from 40 A to 100 A.
