Littelfuse FLNR150ID - RK5 Time-Delay Fuse 150A@250V (200kA AIC)

Littelfuse FLNR150ID is a UL Class RK5 dual-element time-delay fuse designed for circuit protection in low-voltage applications, featuring visual indication for fault detection. Rated for 250V AC systems with a 150A current capacity, it provides 200kA interrupting capacity at rated voltage for reliable overload and short-circuit protection. The fuse measures 7 1/8 inches in length with a 1.59-inch diameter rejection blade construction, weighing 1 lb for secure panel mounting. Certified to CSA, cUL, and UL standards, this Mexico-manufactured component meets industrial safety requirements for motor control centers, HVAC systems, and power distribution equipment where time-delay characteristics prevent nuisance tripping during inrush currents.
