FAQs
The LESRK200 follows standard Edison fuse dimensions with a length of 9.63 in, width of 1.61 in, and height of 1.61 in. It fits typical 1- and 2-pole fuse panels using standard end-cap terminals and electrically isolated end caps for safer wiring in crowded control cabinets. Ensure your enclosure accepts RK1-class fuses and matches the 600 V rating for motor circuits.
Key ratings are 200 A amperage, 200 kAIC interrupt rating, and 600 V voltage rating. These specifications align with protecting medium-to-large motor feeders and inrush-heavy drives. When selecting, confirm the motor’s starting current, short-circuit current, and control voltage compatibility to ensure correct coordination with upstream breakers and starters.
Yes. The LESRK200 is designed for high inrush current motor protection and features a Class RK1 designation with non-indicating construction. This combination supports proper fuse coordination for motor starters in conveyors and pump applications, enabling quick protection action while minimizing nuisance trips during startup.
The fuse is UL Listed and CSA Certified, indicating compliance with recognized safety and performance standards. These certifications simplify supplier qualification, support regulatory audits, and provide assurance to project teams that the protection device meets industry requirements for electrical safety and reliability.
The non-indicating design reduces maintenance complexity by simplifying replacement workflows, while the compact 9.63 in length and standard packaging streamline stocking and interchangeability. Combined with high interrupt capability and robust motor protection, this can reduce unplanned downtime, extend motor life, and lower total cost of ownership in automation-driven production lines.
