FAQs
Yes. LENRK450 is part of the Edison LENRK fuse family and uses the standard Class RK1 form factor with 70/30 brass end caps. It is designed for straightforward integration into existing LENRK assemblies and control panels. Expect standard packaging (one unit per pack) and dimensions that align with typical Edison LENRK applications, simplifying replacement and stocking across motor protection tasks.
The 200 kAIC interrupt rating indicates the fuse can interrupt fault currents up to 200 kiloamps at its rated voltage without exploding or welding shut. This protects motors and drives from high short-circuit currents, reducing motor damage, downtime, and collateral equipment wear in high-energy events commonly seen with heavy industrial loads.
Yes, LENRK450 is suitable for AC motors operated in drives up to 250 Vac with a 125 Vdc alternative. It provides robust motor protection in VFD environments by tolerating inrush conditions while delivering reliable short-circuit interruption. For DC motors or non-standard supply configurations, verify compatibility with the specific drive topology before selection.
LENRK450 carries CSA Certification and UL Listing, ensuring compliance with North American safety standards. It is RoHS compliant, supporting eco-friendly manufacturing and regulatory adherence across global deployments. These certifications simplify procurement for regulated industries and multinational projects.
LENRK450 offers a compact, durable design with electrically isolated end caps and robust brass terminations, reducing wiring errors and wear. The high interrupt rating minimizes costly fault events, while standardization within the LENRK family simplifies stocking and replacements. Over time, this translates to lower maintenance labor, fewer spare parts, and improved system uptime.
