• PINPOINTS OPEN FUSES IMMEDIATELY - gives instant visual indication of any down circuit.
• NO COSTLY DOWNTIME- What could be 20 minutes or more of troubleshooting is now reduced to simply spotting the darkened window on the fuse.
• EXCELLENT FOR CIRCUITS WITH HIGH IN-RUSH CURRENTS- motors, transformers, solenoids, fluorescent lighting - ideal for high efficiency motors which can cause other time delay fuses to open needlessly.
• INCREASED SAFETY- eliminates hazards of poking around an energized panel to find an open circuit.
• 300,000 AMP AC INTERRUPTING- to meet the future needs of increased available currents.
• CURRENT LIMITING- Reduces damage caused by heating and magnetic effects of short-circuit currents.
• SOLID STATE DUAL-ELEMENT TIME DELAY- 10 seconds minimum time delay at 500% of amperage rating eliminates unnecessary downtime caused by power surges or equipment demands. Fast acting short circuit protection can clear the circuit in .008 seconds or less.
• USES LESS ENERGY AND RUNS COOLER- low resistance construction reduces power loss, lowering energy costs. Cooler running fuses give longer switch and component life.
• Ideal Upgrade for Systems using FLS-R Class RK5 Fuses.
• Voltage Rating - 600 Volts AC / DC
• Interrupting Ratings:
  AC: 200,000 rms symmetrical amperes; 300,000 Amps self-certified by Littlefuse
  DC: 20,000 Amperes
• Approvals:
  AC: UL listed Class RK5 fuse; CSA HRC1-R
  DC: 600 Volt MSHA Approved; UL 198M
