Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, 70-600 A data sheet no. 1002
Feature → Business Impact → Application: Time-delay, dual-element design provides controlled inrush handling and rapid but selective short-circuit protection, reducing downtime and extending equipment life in motor drives and conveyor systems used in packaging, printing, and assembly lines. This translates to higher line throughput and lower maintenance costs in continuous-process environments. Feature → Business Impact → Application: 200 A rating with 600 Vac and 300 kAIC interrupt capability ensures robust protection for medium-sized power circuits and switchgear, supporting safer panel design in industrial automation and energy management installations. Feature → Business Impact → Application: Blade-end x blade-end connections and electrically isolated end caps simplify installation, safe maintenance, and quick replacement in retrofit projects or new builds across automotive, plastics, and metal fabrication facilities. Feature → Business Impact → Application: Class RK1 classification and CE marking provide standardization across projects, improving compliance workflows and supplier integration in multi-site manufacturing. Feature → Business Impact → Application: Non-indicating fuse body and standard packaging reduce service time during replacement, while the compact form factor fits 9.63 in length and 1.61 in width enclosures, common in control panels and distribution boards across process industries.

FAQs
The LPS-RK-200SP uses blade-end connections designed for plug-in installation in standard low-voltage panels. It belongs to the Class RK1 family and features electrically isolated end caps to simplify safe maintenance. With a 9.63 in length and 1.61 in width footprint, it matches common Bussmann footprints for easy retrofit or new installs.
Key specs include a 200 A amperage rating, 600 Vac voltage rating, and 300 kAIC interrupt rating at 600 Vac (and 100 kAIC at 300 Vdc). It is a time-delay, dual-element, current-limiting fuse with non-indicating indicators, designed for reliable protection in power distribution and motor protection applications.
Yes. The dual-element, time-delay design handles motor inrush while providing fast short-circuit interruption, making it well-suited for motor protection in control panels, drives, and MCCs. The 200 A rating and high interrupt capability ensure robust protection without nuisance tripping during startup.
The LPS-RK-200SP is CE marked for conformity with European standards. It follows the RK1 class designation for standardized fusing in protection schemes. For compliance verification, Eaton provides a RoHS resource tool to confirm restricted substance conformance for this product line.
The fuse’s time-delay, dual-element design minimizes nuisance trips during inrush events, reducing unplanned downtime and maintenance costs. Its electrically isolated end caps enable safer servicing, and the compact form factor plus standard packaging speeds replacement in both new builds and retrofits, improving overall equipment availability and return on investment.
