FAQs
LENRK2.25 is ideal for motor-protection circuits in industrial drive systems powering small to mid-size motors at 250 V. It fits standard RK1 protection schemes in control panels and motor starters, and pairs with Eaton Edison fuse holders for reliable protection with minimal panel modification. The 2.25 A rating and 200 kAIC interrupt rating help maintain uptime while limiting arcing.
LENRK2.25 provides robust protection with a 200 kAIC interrupt rating, enabling fast fault clearing while tolerating high inrush currents typical of motor start-up. This reduces nuisance trips and protects conductors and drives. The non-indicating design keeps panel visibility clear while preserving protective performance during routine operation.
Yes. The LENRK2.25 carries CSA Certified and UL Listed marks, confirming safety compliance for industrial panels and motor-control circuits. These certifications support design approvals, simplify compliance documentation, and help meet regulatory requirements in a variety of manufacturing and processing environments.
Consider the fuse’s compact form factor (2 in length, 0.56 in width and height) and standard packaging of 10 units per package. The 70/30 brass end caps provide durable connections, and compatibility with standard Edison fuse blocks simplifies installation in existing panels or retrofit projects with limited space.
Capture the amperage rating (2.25 A), voltage rating (250 V), interrupt rating (200 kAIC), and class (RK1). Include certification requirements (CSA, UL), packaging quantity (10), and the catalog number LENRK2.25. Also note the non-indicating status and 70/30 brass end caps to ensure compatibility with existing panel hardware.
