LPJ-300SP - 300 Amp Fuse

When you're replacing a fuse in commercial or industrial electrical equipment, matching the specifications matters—amperage alone doesn't tell the whole story. The Eaton Bussmann series LPJ-300SP is a 300A, 600V Class J fuse with a manufacturer-specified 300 kAIC interrupting rating. It uses a blade-end × blade-end connection and has a non-indicating configuration, giving maintenance professionals several clear identification points when checking compatibility with existing equipment.
