Eaton Edison NCLR45 fuse - Class RK1, UL Listed
Part Number: NCLR45
Quick Summary
The Eaton Edison NCLR45 fuse provides reliable overcurrent protection for industrial control circuits in panelboards and motor control centers. Many engineers struggle with selecting fuses that survive wide ambient temperatures and deliver fast, predictable blow characteristics. This device is UL Listed and CSA Certified, CE Marked, and uses Class RK1 construction for robust, code-compliant protection. For procurement and maintenance teams, that translates into regulatory compliance, reduced downtime, easier audits, and more predictable replacement cycles that lower total cost of ownership. With standard packaging of ten units and a compact 3 in length, it also simplifies stocking and fast field replacements in busy industrial environments.

The NCLR45 fuse features a 45 A, 250 V Class RK1 rating with a 200 kAIC interrupt capability, housed in a durable glass melamine tube. This combination delivers robust short-circuit protection and fast fault clearing, reducing damage to upstream equipment and lowering downtime costs in demanding panels and MCCs. The compact 3 in length and 0.81 in width allow easy replacement in crowded control enclosures, while the non-indicating design minimizes nuisance indicators during routine maintenance. From a procurement perspective, standard packaging of 10 units simplifies stocking and auto-replenishment, supporting lean inventory practices without sacrificing reliability. The device’s CE Mark, UL Listed, and CSA Certified status ensures global compliance across European and North American installations, streamlining audits and cross-border projects. Operators benefit from predictable coordination with upstream protection devices due to RK1’s reliable time-delay characteristics, enabling safer, smoother startups in motor-loaded circuits.
