Eaton KRP-C-1400SP Fuse - Class L, 600 Vac, 300 kAIC
Part Number: KRP-C-1400SP
Quick Summary
The Eaton Bussmann KRP-C fuse provides reliable Class L time-delay protection for high-current electrical feeders. Facilities engineers confront nuisance trips, downtime, and escalating maintenance costs when protecting large motor loads, especially during inrush events. It is CE-marked and RoHS compliant, aligning with global regulatory standards for electrical components. Featuring a 600 Vac and 300 kAIC interrupt capability, it enables selective protection and fast fault clearance without unnecessary panel disconnections. This combination supports simplified procurement, predictable lifecycle costs, and easier spare-parts management in control panels across multiple sites. For engineers optimizing uptime and safety, it pairs well with standard Bussmann KRP-C holders and data sheets.

FAQs
The KRP-C-1400SP is a Bussmann Class L fuse designed to fit standard KRP-C holders and Bussmann fuse blocks. Verify the holder is rated for 1400 A and 600 Vac, and ensure proper clearance for a 10.75 in long device. For best results, pair with compatible Bussmann KRP-C series accessories and follow manufacturer mounting guidelines.
Key ratings include an amperage rating of 1400 A, voltage rating of 600 Vac (and 300 Vdc), interrupting ratings of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, and a 4-second response time at 500% overload. These specs support high-current protection with controlled fault clearance in industrial panels.
Yes. The Class L time-delay design provides selective protection for motor feeders and power distribution panels, accommodating motor inrush while delivering rapid fault interruption to downstream equipment. Its 1400 A rating and 600 Vac capability make it appropriate for large industrial feeders and critical machinery.
The KRP-C-1400SP is CE-marked and RoHS compliant, aligning with European regulatory requirements and sustainability standards. These certifications simplify cross-border procurement and support corporate compliance programs in global facilities.
Technical resources include the Bussmann series KRP-C data sheet No. 1008 and catalog PDFs in the downloads section. These documents provide comprehensive electrical ratings, dimensional data, and installation guidance to support engineering validation and spare-parts planning.
