Feature: Time-delay, current-limiting protection is designed to absorb motor inrush and transient overloads without tripping. Business impact: improves fault tolerance and minimizes unplanned downtime in production lines. Application: motor control centers and starter circuits in 600 V systems. With calibrated coordination against upstream devices, this fuse helps maintain continuity while still interrupting dangerous faults. Feature: High interrupt rating of 200 kAIC at 600 Vac provides robust fault current interruption. Business impact: minimizes damage to switchgear and downstream devices, reducing repair costs after a fault. Application: large drives, power distribution panels, and high-energy feed circuits in manufacturing environments. The rating supports clean interruption of high-energy faults and extends equipment life. Feature: Small footprint and non-indicating design reduces panel space and simplifies retrofits. Business impact: easier cabinet upgrades and minimized wiring complexity. Application: compact installations in machine control cabinets and panelboards where space is at a premium. Feature: RoHS compliant Class L fuse aligns with global regulatory requirements and standard protection architecture. Business impact: ensures regulatory compliance while preserving known Bussmann protection characteristics. Application: multi-national facilities and assemblies that require RoHS conformity; supports environmental and supply chain requirements. Feature: Standard packaging and conventional form factor support easy sourcing and fast procurement. Business impact: reduces lead times and inventory costs, enabling predictable project timelines. Application: new installations and legacy upgrades in plant-wide electrical protection schemes; aligns with Eaton’s Bussmann data sheets for easy cross-reference.

FAQs
Yes. The KRP-CL-300 is a Class L time-delay, current-limiting fuse rated for 600 V and 300 A, designed to integrate with typical Bussmann Class L layouts. Its non-indicating indicator simplifies panel interiors, while its 8.63 in length and standard packaging streamline retrofits and new builds alike.
The device provides current-limiting protection with a 200 kAIC interrupt rating at 600 Vac, allowing safe interruption of high-energy faults. Its time-delay characteristic tolerates motor inrush, reducing nuisance trips during startup while preserving fast clearance of actual faults in 600 V circuits.
The KRP-CL-300 is RoHS compliant, aligning with environmental and material restrictions across global markets. This helps meet regulatory requirements for European and Asian supply chains and supports broader corporate sustainability goals without sacrificing protection performance.
Its small footprint and non-indicating design save panel space and simplify retrofits in crowded control cabinets. The standard packaging and compatibility with Bussmann KRP-CL Class L equipment enable straightforward procurement and consistent protection across motor drives, feeders, and control circuits in industrial environments.
