Core features

  • 200kA interrupting rating provides high ratings at virtually all circuit locations. Economical solutions for high fault circuits. 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.
