FAQs
The KRP-CL-350 uses blade-end x blade-end connections and measures 8.63 inches in length, designed for straightforward integration into standard panelboards and switchgear. Verify compatible bus bars and ensure the panel provides 600 V rating; remove power, insert fuse with clean contact seating, and re-energize. This approach minimizes contact wear and ensures consistent current interruption performance.
Key ratings include a 350 A amperage rating and a 200 kAIC interrupt rating at 600 Vac, making it suitable for protecting heavy motor feeders and high-energy circuits. The voltage rating of 600 V supports typical industrial distribution environments, while RoHS compliance ensures material safety and environmental responsibility.
Yes. The time-delay characteristics of the Class L fuse, combined with current-limiting behavior, help mitigate inrush during motor start-up and reduce nuisance trips. Its 350 A rating supports sizeable motor feeders, and the 200 kAIC interrupt capability provides robust protection against short circuits in demanding industrial environments.
The KRP-CL-350 is RoHS Compliant, aligning with environmental and regulatory expectations for electronics and electrical components. No additional certifications are listed in the provided data, so confirm regional requirements (UL/CE approvals if needed) with the datasheet and local compliance teams for specific deployments.
The fuse’s non-indicating design reduces nuisance alarms in crowded assemblies, while its robust Class L time-delay and current-limiting performance help extend equipment life by preventing arcing and transient damage. Its compact, blade-end configuration simplifies stocking and replacement, supporting lower maintenance labor and faster service turnover in industrial facilities.
