Eaton Bussmann series of AHC fast-acting fuses provide reliable overcurrent protection up to 30A for high voltage applications. The 1/4" x 1-1/4" (6 x 32 mm) 3AB fuse can be applied in Bussmann series fuse holders as a cartridge fuse, offering replaceability, or can be applied in thru-hole installations. The high voltage ratings help reduce required space for overcurrent protection.
