Eaton LPSRK45SPNP Fuse - RK1 Time-Delay Current-Limiting

The time-delay, current-limiting design of the Eaton LPSRK45SPNP fuse provides selective protection during motor startups and surge events while ensuring rapid fault clearance. This reduces nuisance tripping, minimizes unplanned downtime, and supports predictable line performance. In control panels and machine enclosures, it enables safer, smoother operation without sacrificing protection, helping maintain throughput and equipment longevity. Nickel-plated caps enhance durability and corrosion resistance, extending service life in vibration-prone environments common on factory floors. This reduces maintenance costs and downtime caused by cap wear or contact degradation. The fuse remains reliable across frequent cycling and harsh conditions, aligning with uptime targets in automation installations. With 100 kAIC interrupt rating at 600 V DC and 300 kAIC at 600 V AC, the LPSRK45SPNP delivers robust fault energy control for high-energy circuits. The combination of current-limiting action and rapid response protects conductors, terminals, and drives from catastrophic damage. It also supports compliance with electrical protection standards and enables tighter coordination within protection schemes. Rated 600 V and 300 V DC, this RK1-class fuse is versatile for both AC mains and DC bus protection in industrial applications such as conveyors, robotics, and panel boards. Its standardized packaging simplifies replacement and enables easy stocking in multi-fuse assemblies. The standard 5.5 in length fits common RK1 holders, reducing installation time. RoHS compliance and standard Bussmann series packaging streamline procurement and regulatory alignment. The nickel-plated caps and standard form factor minimize field adaptation costs while ensuring consistent performance across the Eaton Bussmann range. For design engineers, specifying LPSRK45SPNP supports safer, compliant, and cost-effective protection across critical power circuits. Physical dimensions and weight further support reliable integration: 5.5 in length, 1.06 in width, 1.06 in height, and a 2.6 lb weight. These specs, together with a standard packaging type, ease mounting in protective enclosures and promote straightforward inventory management.
