Industrial LPJ-80SP Low-Peak Dual-Element Time-Delay Fuse

LPJ-80SP is Bussmann's Low-Peak Class J dual-element time-delay fuse rated for 80 A and 600 VAC, delivering current-limiting protection with an interrupting rating up to 300 kA RMS at 600 VAC. This non-indicating, dual-element device uses a cartridge-body design with blade-type terminals for secure mounting in industrial power-distribution and motor-control panels. The LPJ-80SP features a long-time delay characteristic (minimum 10 seconds at 500% of rated current) to tolerate motor inrush and brief overloads, and its compact 1.13 in diameter by 4.63 in length body fits standard Class J fuse holders. As part of the UL Class J Low-Peak LPJ family, it is rated for 600 VAC and 300 VDC, making it suitable for circuits where both overload protection and fast fault response are required, such as motor starters, drives, and power-distribution blocks in industrial environments. Compatible with standard Class J mounting and designed to protect circuits from short circuits while minimizing let-through energy, the LPJ-80SP provides reliable, current-limiting protection in demanding 600 VAC systems.
