LENRK4.5 is a non-indicating Class RK1 fuse that protects motors against short-circuit faults while minimizing unnecessary inspections. The practical impact is fewer service interventions and shorter downtime windows for critical equipment, especially during batch operations or peak production periods. Inrush tolerance up to 200 kAIC ensures reliable interruption of large surges at motor start-up, reducing stress on wiring, contactors, and transformers and improving overall system reliability in control panels and motor circuits. The 70/30 brass end caps provide robust, low-resistance connections that extend contact life and support repeated insertions in standard fuse holders across conveyor lines and pumps. UL Listed and CSA Certified status supports regulatory compliance, while standard packaging and a 10-unit quantity simplify stocking for manufacturers and service teams. The LENRK4.5’s 2 in length, 0.56 in width, and 0.56 in height enable compact integration in dense control enclosures without sacrificing protection. This device is compatible with the Edison Bussmann line, helping engineers streamline procurement and field replacements with predictable, repeatable performance.
