Eaton BK/LPJ-100SP Fuse - Time Delay, Class J
Part Number: BK/LPJ-100SP
Quick Summary
Eaton Bussmann LPJ fuse is a time-delay, current-limiting protection device designed for industrial panels and motor circuits. For engineers and procurement teams, finding a reliable protection solution that can withstand inrush without nuisance trips is a common challenge. This LPJ fuse meets NEC compliance and the JASO D622 standard, while its Class J form factor ensures predictable coordination in protected circuits. Bulk packaging simplifies stocking and reordering, and the 4.59 in length with a compact 1.12 in profile makes it suitable for dense control enclosures. By using the catalog BK/LPJ-100SP, you gain traceability, faster field swaps, and a scalable protection strategy across multiple machines.

Special features
Rejection style
Time-delay, current-limiting operation enables short-term inrush handling while capping damaging fault currents. This protects downstream devices and reduces unplanned downtime, keeping critical loads safe from short faults. It is especially effective for motor starters, drives, and control circuits in manufacturing lines. Bulk packaging reduces stocking complexity and labor costs, delivering fewer SKUs and faster replenishment for multi-site deployments. The compact 4.59 in length and 1.12 in width fit dense control enclosures, saving panel space and simplifying installation across assemblies. The NEC compliance and JASO D622 alignment provide regulatory confidence for both industrial and automotive-adjacent equipment. The rejection-style feature minimizes the risk of improper fusing on high-volume lines, improving quality control and field reliability. Compatibility with the LPJ family and the BK/LPJ-100SP catalog number ensures traceable, repeatable replacements across projects.

FAQs
BK/LPJ-100SP is designed for standard Class J fuse blocks used in Eaton Bussmann LPJ assemblies. It supports typical motor control and panelboard protections where time-delay coordination is needed. For optimal performance, pair with LPJ-compatible holders and verify current rating against your circuit’s inrush profile and fault current levels.
Catalog Number: BK/LPJ-100SP; Fuse type: Time delay, Current-limiting; Class: Class J; Packaging: Bulk; Size: 4.59 in L Ă— 1.12 in W Ă— 1.12 in H; Weight: 0.22 lb; UPC: 051712749633; Compliances: NEC, JASO D622; Applications: industrial panels, motor control circuits.
Yes. The LPJ-100SP combines time-delay characteristics with current-limiting protection, allowing motor inrush to occur while restricting peak fault currents. This reduces nuisance trips and helps maintain production continuity in panels housing motor starters, conveyors, and other automated equipment.
The BK/LPJ-100SP is NEC compliant and aligns with JASO D622, providing confidence for industrial and automotive-adjacent applications. While not a CE or IP rating, these standards support safe, code-compliant installation and reliable performance in demanding environments.
Bulk packaging and a single catalog number simplify stocking, reorder processes, and BOM management across sites. The 4.59 in length and standard Class J form factor speed up replacements, while the UPC enables efficient asset tracking and warranty/service administration, contributing to lower total cost of ownership.
