Instructions for Use:

1. Installation:

   • Ensure that the circuit is de-energized before installing or replacing the fuse.
   • Insert the fuse into the appropriate fuse holder or fuse block.
   • Ensure the fuse is securely seated to avoid loose connections.

2. Operation:

   • The fuse is designed to protect circuits from overcurrent conditions. It will blow (open) when the current exceeds its rated capacity.
   • Regularly inspect the fuse and replace if it appears damaged or has blown.

3. Replacement:

   • Always replace the fuse with one of the same type and rating.
   • Do not use fuses with higher ratings as this can lead to overheating and potential fire hazards.

4. Storage:

   • Store fuses in a dry, cool place away from direct sunlight and extreme temperatures.
   • Keep fuses in their original packaging until ready to use to prevent damage.

5. Safety Precautions:

   • Never bypass or bridge a fuse.
   • Always follow local electrical codes and regulations.
   • Use appropriate personal protective equipment (PPE) when handling electrical components.
