Eaton KRP-C-1100SP Fuse - 300 kAIC at 600 Vac
Part Number: KRP-C-1100SP
Quick Summary
The KRP-C-1100SP fuse from Eaton Bussmann protects industrial power circuits with time-delay, current-limiting performance. Engineers often wrestle with nuisance trips during inrush events or undersized interrupt ratings that threaten machine uptime. This Class L device is CE marked and RoHS compliant, designed for bolted blade end installations and broad AC/DC compatibility. Its compact form and Bussmann series pedigree translate into easier panel assembly, faster commissioning, and lower total cost of ownership across feeders and motor drives. In short, you get reliable protection, regulatory compliance, and a predictable protection strategy for demanding industrial environments. Designed for industrial automation configurations, it pairs well with standard fuse blocks and power distribution panels.

FAQs
The KRP-C-1100SP uses bolted blade end connections and follows the Bussmann KRP-C form factor, enabling straightforward installation in standard fuse blocks and power distribution panels. Its compact dimensions (10.75 in L, 2.78 in W and H) fit tightly packed electrical assemblies commonly used in industrial control cabinets.
Key specs include 1100 A amperage rating, 600 Vac voltage rating, 300 kAIC interrupt rating at 600 Vac, and 100 kAIC at 300 Vdc. The fuse is time-delay (slow-blow) Class L, designed to handle inrush without nuisance tripping while maintaining strong fault protection.
Yes. It is CE marked and RoHS compliant, ensuring regulatory alignment for many European and global applications. The fuse’s non-indicating indicator supports maintenance planning in dense panel environments.
Ideal for motor feeders, process control circuits, and high-inrush power distribution, where reliable protection plus inrush tolerance minimizes downtime. The 4-second response at 500% load supports coordinated protection without sacrificing startup safety.
Install with standard Bussmann KRP-C blocks using bolted blade ends, confirm correct amperage and voltage ratings, and plan for RoHS/CE compliance checks. The non-indicating design reduces ongoing monitoring needs, while the robust interrupt ratings safeguard downstream equipment.
