Eaton Specification Sheet - LPS-RK-150SP-TP
Feature → Business Impact → Application: The LPS-RK-150SP-TP is a low-peak, time-delay, current-limiting fuse in the RK1 class, which reduces nuisance trips while protecting circuits during inrush events. This translates to smoother machine startups and lower maintenance costs in automation panels and motor drives. Application: use in control cabinets and power distribution panels where steady inrush handling and fast fault clearance are essential. Feature → Business Impact → Application: With a 150 A amperage rating and high interrupt ratings of 100 kAIC at 300 Vdc and 300 kAIC at 600 VAC, it provides robust fault protection for large equipment and critical loads. Application: suitable for industrial automation equipment and process control systems demanding strong fault tolerance. Feature → Business Impact → Application: Tin-plated material and RoHS compliance improve reliability and supplier readiness, reducing contact corrosion and easing global sourcing. Application: compatible with standard Bussmann-series assemblies and multi-region deployments. Feature → Business Impact → Application: Standard packaging and non-indicating design simplify stocking and replacement in high-volume maintenance environments, lowering total cost of ownership. Application: ideal for OEM assembly lines and panel builders seeking straightforward component reuse. Feature → Business Impact → Application: The fuse’s physical dimensions (9.63 in length, 1.61 in width, 1.61 in height) and 2 lb weight enable predictable fit in common DIN-rail or vertical panel layouts. Application: quick, risk-free retrofits in existing equipment without enclosure redesign.

FAQs
The LPS-RK-150SP-TP uses standard Bussmann-series packaging designed for straightforward panel installation. It fits common fuse holders used in industrial control and power-distribution cabinets, with a 9.63 in length and 1.61 in cross-section, making it compatible with typical enclosure layouts and mounting rails in mid- to high-density panels.
Key specs include an amperage rating of 150 A, voltage ratings of 600 V and 300 Vdc, and interrupt ratings of 100 kAIC at 300 Vdc and 300 kAIC at 600 VAC. It is a time-delay, current-limiting fuse designed to tolerate inrush while protecting circuits from short circuits.
Yes. The LPS-RK-150SP-TP is specified for 300 Vdc operation with 150 A capacity and high DC interrupt capability, making it suitable for DC-powered automation panels, drives, and control circuits when within its rated values.
The fuse is RoHS compliant, ensuring restricted use of hazardous substances and facilitating compliance with global environmental and quality standards in many regions.
Its high interrupt ratings reduce downtime during faults, tin-plated contacts resist corrosion for longer life, and standard packaging simplifies sourcing and stocking. Together, these factors lower maintenance intervals and total cost of ownership while improving system reliability.
