Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, up to 600 A data sheet no. 1001
Feature → Business Impact → Application: Time-delay, dual-element design provides inrush tolerance and rapid fault clearing, reducing nuisance trips while protecting costly motors and drives in machine rooms. This translates to lower downtime and higher line efficiency in panelboards and MCCs. Application: Use in motor control centers and feeders where startup surges are common, such as stamping presses or conveyors. Feature → Business Impact → Application: 60 A current rating with high interrupt ratings (300 kAIC at 600 Vac, 100 kAIC at 300 Vdc) delivers robust short-circuit protection, improving equipment longevity and safeguarding personnel. Application: Ideal for high-energy industrial installations requiring reliable fault interruption. Feature → Business Impact → Application: Ferrule end x ferrule end connections and electrically isolated end caps simplify installation and maintenance, minimizing commissioning time and reducing wiring errors in new builds and retrofits. Application: Retrofit projects and new panel builds seeking standardization with RK1 class fuses. Feature → Business Impact → Application: Non-indicating fuse with clear status through indirect monitoring in controlled environments reduces unnecessary debugging during routine maintenance. Application: Critical systems where minimal visual maintenance is preferred. Feature → Business Impact → Application: 10-unit packaging supports kanban and stock control, enabling lean procurement and quick replacements in spare-part inventories. Application: OEM build-outs and service fleets seeking consistent, ready-to-deploy components.

FAQs
The LPS-RK-60SP uses ferrule ends for easy, secure connections at both ends, designed for panelboard and MCC installations. Its standard packaging of 10 units supports streamlined stocking, and the ferrule-to-ferrule configuration reduces wiring complexity during retrofit or new-build projects.
Its time-delay, dual-element construction tolerates startup surges while preserving fault protection. With a 60 A rating and high interrupt capability (300 kAIC at 600 Vac, 100 kAIC at 300 Vdc), it minimizes nuisance trips during motor starts and cycling operations.
Ideal for panelboards, motor control centers, and feeders in industrial settings requiring reliable 60 A protection at up to 600 Vac or 300 Vdc. Its Class RK1 designation aligns with common industry standards, making it suitable for European and other markets while supporting safe, robust machine protection.
The LPS-RK-60SP is CE marked, confirming compliance with European safety and performance standards. For broader regulatory requirements, consult the full datasheet and Eaton compliance resources, as additional certifications may vary by region and application.
Durable dual-element design and high interrupt ratings extend service life and reduce unplanned outages. The non-indicating indicator minimizes maintenance checks, while ferrule end connections and 10-piece packaging simplify stocking, replacements, and downtime planning in OEM builds and service fleets.
