Cooper Bussmann LPS-RK-225SP Dual Element Time Delay Fuse

Cooper Bussmann LPS-RK-225SP is a Low Peak Dual Element Time Delay Fuse, a protective device designed to interrupt current when overcurrent conditions persist beyond its deliberate delay, enabling circuits to survive transient overloads without immediate shutdown. As a dual-element, time-delay fuse, it tolerates short surges and temporary overloads—two features that reduce nuisance trips while maintaining protection against sustained faults that could damage wiring, equipment, or components. The LPS-RK-225SP designation identifies this specific unit within Cooper Bussmann's Low Peak Series, signaling a compact form factor combined with time-delay operation and dual-element construction that set it apart from fast-acting fuses. Because of its low-peak design, the LPS-RK-225SP helps limit peak current impact during transient events, supporting more stable operation in electrical panels, control circuits, and other installations where brief current spikes are common.
