Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, up to 600 A data sheet no. 1001
The LPS-RK-6/10SP uses a time-delay, dual-element design to provide selective protection for circuits with brief inrush or motor start-up, reducing nuisance trips and preserving equipment life in motor drives and control panels. This improves uptime and lowers maintenance costs by allowing legitimate surges to pass without triggering a fault condition. With an interrupt rating of up to 300 kAIC at 600 VAC and 100 kAIC at 300 VDC, it offers robust fault clearance even in high-energy industrial systems, protecting downstream devices and reducing the risk of cascading outages. Its Class RK1 construction, standard 5 in length and standard packaging, simplifies retrofits and ongoing stocking, enabling faster installation and consistent protection across existing RK1 bases. Electrically isolated end caps enhance maintenance safety, minimizing shock risk during servicing. CE marking and the 0.6 A rating support precise protection coordination in EU operations while enabling straightforward procurement and compliance across global facilities. This fuse is a versatile fit for industrial control panels, motor starters, and power distribution networks, delivering reliable protection within a compact footprint.

FAQs
The LPS-RK-6/10SP is a 5 inch long, dual-element, time-delay, current-limiting fuse designed for RK1 holders. It fits standard Bussmann RK1 assemblies with a 0.81 inch width, enabling straightforward retrofit and minimal panel modification while maintaining reliable protection for industrial controls.
This fuse provides a 0.6 A amperage rating, 600 VAC and 300 VDC voltage ratings, with interrupt ratings up to 300 kAIC at 600 VAC and 100 kAIC at 300 VDC. It responds within about 10 seconds at 500% overload, balancing inrush tolerance with rapid fault clearance to protect downstream equipment.
Yes. Its time-delay characteristic accommodates motor startup surges while its current-limiting behavior protects wiring and drives. The fusion of RK1 compatibility, compact form, and strong interrupt ratings makes it a practical choice for motor starters, control panels, and automation lines in manufacturing environments.
The fuse is CE marked, aligning with European safety standards. It belongs to the Class RK1 family and features an electrically isolated end cap for safer maintenance in crowded panels. These attributes support compliant installations and dependable protection across European and global facilities.
Using a time-delay, dual-element fuse reduces nuisance trips during startup, lowering unplanned downtime. The robust interrupt ratings and RK1 compatibility streamline spare-part inventories and replacements, while standard packaging and known dimensions shorten installation time, delivering improved uptime and lower total cost of ownership in large-scale automation deployments.
