Cooper Bussmann LPS-RK-40 - RK1 Fuse 40A 600V (300kA AIC)

Cooper Bussmann LPS-RK-40 is a low-voltage current-limiting fuse designed for circuit protection in industrial and commercial electrical systems. Rated for 600V AC/DC operation with a 40A current capacity, it features a single-barrel RK1 class construction with a 0.81-inch diameter for reliable high-interrupting capacity (300kA at 600V). The fuse meets stringent industry standards for overcurrent protection in demanding environments. Typical applications include motor control centers, switchgear, and power distribution panels where selective coordination and short-circuit protection are critical.
