Eaton LPJ-225SP Fuse - Class J Time-Delay, 300 kAIC
Part Number: LPJ-225SP
Quick Summary
The Eaton LPJ-225SP fuse provides reliable time-delay protection for motor circuits and control panels. Nuisance trips from inrush currents can drive downtime and maintenance costs if protection isn’t matched to load. This Class J device is CE marked and RoHS compliant, with a dual-element current-limiting design that enables fast, selective fault clearing. Built for straightforward field installation with bolted blade ends and a compact form factor, it supports scalable protection in industrial and commercial power distribution. As part of the Bussmann series, LPJ fuses deliver compatibility with standard fuse blocks and spare parts availability, improving procurement velocity for electrical protection schemes.

FAQs
The LPJ-225SP is a Class J fuse with bolted blade end connections designed for standard Bussmann series fuse blocks and panels. It fits motor circuits and control panels that require a 225 A rating, 600 Vac/300 Vdc voltage, and a compact 7.13 in length footprint, enabling straightforward field replacement and scalable protection in existing switchgear.
It uses a time-delay, dual-element current-limiting design to tolerate motor inrush while still delivering fast fault clearing. This results in lower nuisance trips during startup and controlled interruption during faults, with an interrupt rating of 300 kAIC at 600 Vac, protecting downstream equipment and reducing downtime.
Yes. The LPJ-225SP is CE marked and RoHS compliant, aligning with European regulatory standards for electrical protection devices. This ensures regulatory compatibility in global installations and supports environmentally responsible procurement practices across the supply chain.
Non-indicating fuses require external sensing or diagnostic tools to confirm status, so plan for periodic electrical checks and panel-mounted indicators or troubleshooting instrumentation. The robust Class J design and bolted blade ends simplify replacement and reduce support complexity in busy control cabinets.
The LPJ-225SP improves reliability by reducing nuisance trips and providing fast fault clearing, which lowers unplanned downtime and maintenance labor. Its standardization with Bussmann series inventories also shortens spare-part lead times, while its high interrupt rating protects downstream equipment, potentially extending motor life and overall system uptime.
