KRP-C_SP Class L Low-Peak time-delay fuses

Time-delay Class L fuses — 4 seconds (minimum) at 500% rated amps. Use KRP-CL for current ratings under 601 A. 

Ratings 

• Volts 

• 600 Vac (or less) 

• 300 Vdc (601-2000 A, 3000 A) 

• Amps 601-6000 A 

• IR 

• 300 kA RMS Sym. 

• 100 kA DC

Features 

• Time-delay of 4 seconds at 5 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 300 kA 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 

Typical applications 

• Large distribution switchboards 

• Power panelboards 

• Large machinery disconnects
