The Bussmann LPJ-6SPI is a 6A, 600V Class J low-peak, dual-element time-delay fuse with permanent indication, part of the LPJ family designed for 50/60 Hz AC systems. It’s intended to tolerate brief inrush currents in panel mains, machinery disconnects, and industrial-control circuits without nuisance openings. The fuse measures roughly 2-1/4 inches long (57 mm) and 13/16 inch in diameter, and its built-in indication provides a clear status at a glance for easier maintenance.
