Bussmann by Littelfuse LPS-RK-1-1/4SP is a Low Peak, RK1-class current-limiting fuse with a time-delay, dual‑element design housed in a cartridge body and rated at 1-1/4 A (1.25 A). As part of the LPS-RK family, this fuse delivers reliable interruption for circuits protected up to 600 VAC and 300 VDC, with interrupting ratings of 300 kA at 600 VAC and 100 kA at 300 VDC. It is non-indicating, offering protection without an integrated fault indicator. The LPS-RK-1-1/4SP supports fast fault clearance while tolerating brief overloads thanks to its time-delay characteristic, making it suitable for circuit protection in industrial equipment and power distribution environments that require RK1 protection. This variant’s cartridge construction and RK1 rating ensure compatibility with standard Bussmann RK1 fuse holders and assemblies, providing a straightforward replacement option in compatible control panels and distribution systems.
