LPN-RK-1SP - Eaton Bussmann Class RK1 Time-Delay Dual-Element 1A 250Vac/125Vdc Fuse

LPNRK1SP

LPN-RK-1SP is an Eaton Bussmann Series Class RK1 time-delay, dual-element, current-limiting fuse rated 1 ampere at 250 Vac and 125 Vdc.

This non-indicating fuse delivers high interrupting capacity with 300 kA at 250 Vac and 100 kA at 125 Vdc, making it ideal for motor protection, feeder circuits, transformers, and general-purpose applications. The dual-element design provides time-delay protection with an 8-second response at 500% rated current, protecting against single-phase motor damage while allowing 130% FLA sizing for backup motor protection. Current-limiting technology reduces destructive thermal and magnetic forces during short-circuit events, with no venting of arc or molten metal. Ferrule-end connections ensure secure installation in standard fuse holders.
