KRP-C-SP
Low-Peak Class L time-delay fuse in ratings from 601 to 6000 amps. Time-delay four (4) seconds (minimum) at 500% rated amps allows closer sizing on large motor loads combined with Class L current limitation.
Selective coordination ratio of 2:1 within the Low-Peak family (LPJ Class J, NPN 250V Class RK1, LPS 600V Class RK1) prevents electrical shutdowns from extending beyond the failed circuit.
300kA RMS Sym. Interrupting rating provides adequate ratings without obsolesence for all electrical systems big and small.

Features
- Time delay of four seconds at five times rating allows closer sizing on large motor loads combined with Class L current limitation
- Selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit
- Interrupting rating of 300kA RMS symmetrical provides adequate ratings without obsolescence for all electrical systems, big or small
- Quality construction, using high-grade materials, provides lower watts loss and operating temperatures with superior arc quenching during current-limiting action
