Eaton LPJ-5SP Fuse - Class J Time-Delay, Dual-Element
Part Number: LPJ-5SP
Quick Summary
The Eaton LPJ-5SP fuse delivers time-delay protection for motor circuits and control panels. Engineers often face nuisance trips during motor start-up and limited replacement options in compact enclosures. Built as CE marked and RoHS compliant with Class J construction, it also features dual-element protection for reliability. Non-indicating by design, it is ideal where footprint and serviceability matter, while ferrule-end connections simplify installation in panelboards. In broader terms, the 5 A rating, 600 VAC operation, and 300 kAIC interrupt rating support regulatory compliance and system uptime, making it a dependable choice for industrial protection across motor-driven applications.

Feature: Time-delay, dual-element current-limiting design. Business impact: Handles motor inrush without nuisance tripping while limiting fault current, reducing downtime and extending component life. Application: Protects driven equipment in industrial control panels and motor starters. Feature: Class J construction with non-indicating status. Business impact: Meets common industry standards without visual indicators, saving panel space and simplifying procurement. Application: Typical in compact enclosures where remote status is tracked by other diagnostics. Feature: 600 VAC / 300 VDC voltage rating with 5 A rating. Business impact: Suitable for mixed AC/DC systems, enabling a single protection strategy across equipment. Application: Industrial drives and control circuits requiring robust protection. Feature: High interrupt ratings of 300 kAIC at 600 VAC and 100 kAIC at 300 VDC. Business impact: Provides margin for short-circuit events, enhancing system resilience and safety. Application: Large motor feeders and high-inrush service feeders. Feature: Ferrule end x ferrule end termination and standard packaging. Business impact: Quick, repeatable installation with reliable mechanical contact and easy replacement. Application: Serviceable in retrofit projects and new builds alike. Feature: Compliance and documentation options (CE, RoHS, datasheets). Business impact: Ensures regulatory alignment and trusted sourcing, aiding audits and supplier qualification. Application: Aerospace, automotive-adjacent, and general industrial environments where traceability matters.
