Eaton LPJ-100SP Fuse - Class J Time-Delay Dual-Element
Part Number: LPJ-100SP
Quick Summary
The Eaton LPJ-100SP fuse protects industrial control circuits with time-delay, dual-element current limiting in power-distribution panels. A common pain point is nuisance trips during motor startup or brief fault currents, which can halt production. RoHS compliant Class J designation supports sustainable assembly practices, while the series' interrupting ratings toward 300 kA at 600 VAC and 100 kA at 300 VDC reinforce safety. In practice, the LPJ-100SP helps improve panel reliability and uptime by combining fast response with selective protection for downstream devices. Manufacturers benefit from compact 1x1 in footprint and RoHS compliance when standardizing parts across sites. Its 1 in length, width, and height makes it straightforward to drop into existing Class J fuse holders without rearranging panel layouts.

Feature → Business Impact → Application: The LPJ-100SP uses time-delay, dual-element current limiting to tolerate motor inrush while preventing catastrophic faults, reducing downtime and extending equipment life in motor control centers. This translates to lower maintenance costs and safer panel enclosures in high-current environments such as packaging lines and material-handling systems. Application-wise, it fits standard Class J fuse blocks and Bussmann LPJ devices, enabling straightforward retrofits and consistent stocking across facilities. The RoHS compliant design supports sustainable manufacturing practices and simplifies procurement for globally distributed sites. Compatibility with 1 in x 1 in footprints streamlines panel redesigns and minimizes cabinet rework during upgrades or expansions. A common objection—device coordination—is addressed by its explicit current rating of 100 A and high interrupting capacity, which preserves upstream protection margins while delivering selective protection downstream.

FAQs
LPJ-100SP is a 1x1 inch Class J non-indicating time-delay fuse intended for Bussmann LPJ fuse blocks and standard Class J holders. Verify that the fuse block supports 100 A current rating and that panel clearance and busbar connections meet safety and electrical code requirements. The unit weighs about 1 lb and is RoHS compliant for green manufacturing.
LPJ-100SP provides a 300 kA interrupting rating at 600 VAC and 100 kA at 300 VDC, with time-delay and dual-element current limiting. This performance supports protection for motor loads, drives, and power distribution where high fault currents can occur. It is RoHS compliant and designed for reliable operation in harsh industrial environments.
Yes. The LPJ-100SP is a Class J, time-delay, dual-element fuse ideal for motor protection in control panels. The time-delay characteristic accommodates startup inrush, while current-limiting confines damage during faults. Use with compatible LPJ fuse blocks and coordinate upstream protection to maintain selectivity and minimize downtime.
LPJ-100SP is RoHS compliant. The Class J designation reflects standardized performance, while Eaton's datasheets and catalogs provide guidance on regional listings such as UL or CE where applicable. Always consult the datasheet for your specific regulatory requirements and ensure compliance with local electrical codes.
Implementing the LPJ-100SP can lower maintenance costs by reducing nuisance trips, thanks to its time-delay protection and robust interrupting rating. The compact 1x1 in form factor simplifies panel layouts, easing stocking and replacements. Overall, this fuse supports higher uptime, predictable protection, and smoother long-term operational efficiency in industrial facilities.
