Bussmann series Fuseology
Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, up to 600 A data sheet no. 1001
Time-delay, dual-element design delivers selective protection while tolerating short inrush transients, reducing unnecessary outages and equipment wear. This improves overall line reliability and extends motor and control circuit life, translating to lower maintenance costs and higher uptime in production lines. The current-limiting capability helps contain fault energy, safeguarding wiring insulation and preventing cascading damage in feeder circuits. With a 300 kAIC interrupt rating at 600 Vac, systems experience rapid, dependable clearing of faults, supporting safer startup sequences for machine tools and conveyors. The electrically isolated end caps simplify field installation, reduce risk during maintenance, and enable safe replacement without disconnecting downstream components. Its compact 5 in length and 0.81 in width fit compact electrical cabinets, enabling more usable space for wiring and future expansion. The standard packaging and Bussmann-series compatibility support quick stocking and consistent performance across multi-panel deployments, while the 0.8 A rating provides precise coordination with upstream protection strategies in control panels and MCCs.

FAQs
The LPS-RK-8/10SP fits standard 5 inch depth enclosures and uses electrically isolated end caps for safer maintenance. Its dual-element construction and 0.81 inch square body simplify mounting, while its 10-pack quantity supports consistent stocking across facilities. Ensure panel clearance for the 0.81 inch width and allow space for wiring and cooling in high-density racks.
This fuse is rated at 0.8 A with a voltage rating of 600 Vac and 300 Vdc. It provides a 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc, with a 10 second response at 500% overload. These specs enable reliable protection of control circuits and motor loads while tolerating startup surges.
Yes. Its time-delay feature accommodates motor inrush without nuisance tripping, and the current-limiting design helps minimize fault energy in motor circuits. The Class RK1 construction aligns with common industry protection schemes, providing predictable coordination with upstream fusing and circuit breakers in motor control centers and machine builds.
The LPS-RK-8/10SP is CE Marked, indicating conformity with European electrical safety requirements. This certification supports compliance in multinational manufacturing environments and simplifies cross-border procurement for systems integrated with European equipment standards.
The combination of time-delay operation, high interrupt rating, and durable construction reduces unplanned downtime due to nuisance trips and catastrophic failures. Electrically isolated end caps simplify replacement, and standard packaging plus compatibility with Bussmann-series parts streamline stocking, field service, and maintenance planning, delivering lower lifecycle costs and improved uptime in automated production lines.
