Eaton LPN-RK-60SP fuse - Class RK1, 60 A, 300 kAIC
Part Number: LPN-RK-60SP
Quick Summary
Eaton LPN-RK-60SP fuse is a Class RK1 time-delay device designed to protect industrial power circuits. This dual-element, current-limiting fuse helps prevent nuisance trips while maintaining robust protection for motors, drives, and control panels. In demanding environments, users require reliable interrupting capability and predictable timing, which this fuse delivers. With CE marking and a high 300 kAIC interrupt rating at 250 Vac (and 100 kAIC at 125 Vdc), it supports compliant, safer electrical distribution. For panel builders and maintenance teams, the LPN-RK-60SP offers straightforward installation, extended operational life, and consolidated protection in one compact package, reducing downtime and simplifying spare-part inventory. It is a prudent choice for modernizing protection schemes where performance and traceability matter most.
