Eaton KRP-C-3000SP Fuse - Class L, 3000 A, 600 Vac CE RoHS
Part Number: KRP-C-3000SP
Quick Summary
The Eaton Bussmann KRP-C-3000SP fuse protects high-current circuits in power distribution and motor systems. In industrial environments, nuisance trips and lengthy fault-clear times can cause costly downtime; this device delivers selective protection with a time-delay characteristic that tolerates inrush while still interrupting severe faults quickly. The fuse carries Class L coordination and is CE marked with RoHS compliance for global deployment, giving engineers confidence in safety and regulatory adherence. Its bolted blade-end connections and standard packaging simplify panel retrofits and new installations alike, reducing commissioning time. By combining high interrupt capacity with predictable response, it supports reliable protection strategies and lower total cost of ownership for critical loads.

Bussmann series KRP-C 2001 to 6000A Class L fuse data sheet No. 1009
High amperage protection enables safeguarding large feeders and motor drives without overburdening upstream fuses, reducing unexpected outages and enabling steady production. The Class L time-delay design tolerates startup surges while delivering current-limiting action during fault events, improving selectivity between devices and minimizing unnecessary shutdowns in complex panel layouts. With an impressive interrupt rating of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, it provides robust fault clearance, lowering the risk of cascading failures in critical power paths. The bolted blade-end connections and standard packaging ensure straightforward installation and reliable electrical contact, supporting faster maintenance and retrofits in existing equipment. Certifications such as CE and RoHS further streamline global deployment and supplier compliance across multinational facilities, while the 600 Vac / 300 Vdc ratings align with common industrial standards for motor and drive applications. This combination delivers measurable improvements in reliability, safety, and total cost of ownership for industrial automation environments.

FAQs
Yes. The KRP-C-3000SP uses bolted blade-end connections designed for bolted assembly in standard electrical panels. Its dimensions (10.75 in length, 5.03 in width, 5.03 in height) and standard packaging simplify retrofits and new installations alike. This compatibility reduces field modification time and ensures reliable contact pressure, helping to maintain consistent protection across motor and power-distribution circuits.
The KRP-C-3000SP is rated for 3000 A with voltage ratings of 600 Vac and 300 Vdc. It provides an interrupt rating of up to 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, with a response time of about 4 seconds at 500% overload. These specs support fast fault clearance while tolerating startup surges in heavy motor loads.
This fuse is ideal for large motor protection, high-current feeders, and power distribution panels in manufacturing, process, and energy-intensive industries. Its Class L time-delay characteristic enables inrush tolerance without compromising protection, making it suitable for HVAC drives, conveyors, and large pumps where nuisance trips must be minimized and safe shutdown is essential during faults.
The KRP-C-3000SP is CE marked and RoHS compliant, supporting global deployment and regulatory adherence. While not every regulatory region requires the same certifications, these two indicate conformance to essential European safety and environmental standards, simplifying cross-border procurement and supplier qualification for multinational facilities.
Installation is streamlined by standard packaging and bolted blade-end connections, reducing commissioning time. The fuse’s high interrupt capacity and time-delay coordination minimize nuisance trips and downtime, contributing to higher equipment availability. Over the life of a protected motor or distribution circuit, these factors translate into lower maintenance costs and improved asset uptime, delivering measurable ROI for capital-intensive automation projects.
