Eaton LPN-RK-600SP Fuse - Class RK1 Time-Delay
Part Number: LPN-RK-600SP
Quick Summary
Eaton Bussmann LPN-RK-600SP fuse provides reliable time-delay, dual-element protection for electrical panels and motor circuits. This design helps mitigate nuisance trips and downtime caused by short-term inrush or fault conditions. It carries CE Marked and RoHS compliant certifications, supporting regulatory compliance in global installations. Class RK1 coordination, with current-limiting technology, means safer, more predictable protection for downstream equipment. In practice, this fuse delivers robust protection with straightforward integration in blade-end DC/AC systems, while offering a favorable total cost of ownership through reduced maintenance and longer service intervals.

Bussmann series Low-Peak 250 V LPN Class RK1 time-delay fuses,1/10-60 A data sheet no. 1003
Feature → Business Impact → Application: Time-delay, dual-element design provides selective interruption during transient faults and reduced nuisance trips, improving line continuity in motor drives and feeders. This translates to lower downtime and fewer unplanned maintenance events in industrial environments; ideal for panel protection and control circuits. Feature → Application compatibility → The LPN-RK-600SP uses blade end x blade end connections and electrically isolated end caps, enabling quick drop-in installation in standard enclosures and safer wiring practices, reducing field rework. Feature → Benefits of current-limiting with high interrupt capability → In a fault condition, the fuse limits arc energy, protecting personnel and surrounding equipment, while maintaining reliability in 250 Vac and 250 Vdc applications. Feature → Certifications and compliance → CE Marked and RoHS compliant product supports global regulatory requirements, easing procurement and documentation for modern plant standards. Feature → Class RK1 and non-indicating operation → Predictable coordination with upstream fuses and minimal visual maintenance, improving reliability in high-density electrical panels. Feature → Technical performance → With 600 A rating and 300 kAIC at 250 Vac, this device meets demanding industrial protection needs, supporting efficiency gains and safer operations.

FAQs
Yes. The fuse uses blade end x blade end connections and comes with an electrically isolated end cap, allowing straightforward drop-in installation in common panel layouts without special adapters.
It is rated for 600 A, with an interrupt rating of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc, and a voltage rating of 250 Vac / 250 Vdc, making it suitable for high-demand AC and DC circuits.
Best suited for electrical protection in switchgear, motor control centers, control panels, and feeders where inrush conditions occur, providing selective protection while minimizing nuisance trips.
The device is CE Marked and RoHS compliant, aligning with common regulatory and environmental requirements for global installations.
Its dual-element, time-delay design reduces nuisance trips from inrush, while current-limiting minimizes arc energy, lowering downtime and maintenance costs; the non-indicating form simplifies inspections and the electrically isolated end caps enhance safety during servicing.
