2 ආරක්ෂිත තොරතුරු

අවවාදයයි: Electrical shock hazard. Improper installation or handling of electrical components can result in serious injury or death. Always follow these safety guidelines:

• Always disconnect power to the circuit before installing, inspecting, or replacing fuses.
• Use only fuses with the correct voltagඊ සහ amperage ratings for the specific application. Using an incorrect fuse can lead to inadequate protection or circuit damage.
• බයිපාස් කරන්න එපා හෝ ටීamper with fuses.
• If you are unsure about any electrical work, consult a qualified electrician.
• Wear appropriate personal protective equipment (PPE), such as insulated gloves and safety glasses, when working with electrical circuits.

3. නිෂ්පාදන අවසන්view

The Littelfuse FLM3-2/10 FLM3.20 is a cartridge fuse designed for reliable overcurrent protection. It features a 3-2/10 Amp current rating and a 250 Volt voltage rating, suitable for various electrical applications. The fuse is constructed from ceramic, metal, and plastic components, and is designed for through-hole mounting.

4. ස්ථාපනය සහ සැකසුම

Follow these steps for safe installation or replacement of the fuse:

1. බලය විසන්ධි කරන්න: Ensure that the main power supply to the circuit is completely turned off and locked out, if applicable. Verify with a voltagඊ පරීක්ෂක.
2. ෆියුස් රඳවනය හඳුනා ගන්න: Locate the fuse holder or circuit board where the fuse is to be installed or replaced.
3. පැරණි ෆියුස් ඉවත් කරන්න (අදාළ නම්): Carefully remove the old or blown fuse from its holder. Note its orientation if it's a directional fuse (though cartridge fuses are typically non-directional).
4. Verify Ratings: Confirm that the new Littelfuse FLM3-2/10 FLM3.20 fuse matches the required amperage (3-2/10 Amp) සහ වෙළුමtage (250V) ratings for the circuit.
5. නව ෆියුස් එකක් ඇතුළු කරන්න: Insert the new fuse into the fuse holder. For through-hole mounting, ensure the leads are correctly aligned with the holes on the circuit board or terminal block.
6. ආරක්ෂිත සම්බන්ධතාවය: Ensure the fuse is securely seated in its holder or properly soldered if it's a permanent through-hole mount.
7. බලය ප්‍රතිස්ථාපනය කරන්න: Once the fuse is securely installed, restore power to the circuit.

5. මෙහෙයුම් මූලධර්මය

The Littelfuse FLM3-2/10 FLM3.20 fuse functions as a sacrificial device designed to protect electrical circuits. When an overcurrent condition occurs (current exceeding 3-2/10 Amps), the metallic element inside the fuse melts, creating an open circuit and interrupting the flow of electricity. This prevents damage to more expensive components or wiring downstream from the fuse. The fuse does not require any active "operation" by the user; its function is passive and automatic upon an overcurrent event.

6. නඩත්තු කිරීම

Fuses are generally maintenance-free components. Their primary function is to blow and protect the circuit. Regular maintenance involves:

• වරින් වර පරීක්ෂා කිරීම: Visually inspect fuses during routine equipment maintenance for any signs of damage or discoloration, though a blown fuse is often not visually obvious without removal.
• ආදේශනය: A blown fuse must always be replaced with a new fuse of the exact same type, amperage, සහ voltage rating (e.g., Littelfuse FLM3-2/10 FLM3.20). Never attempt to repair a blown fuse.

7. දෝශ නිරාකරණය

If a fuse blows, it indicates an overcurrent condition in the circuit it protects. Follow these troubleshooting steps:

1. පිඹින ලද ෆියුස් හඳුනා ගන්න: Disconnect power and visually inspect the fuse. Some fuses have an indicator, or you can use a multimeter to check for continuity.
2. Investigate Cause: Before replacing the fuse, identify and rectify the cause of the overcurrent. Common causes include:
   • Short circuits in wiring or components.
   • Overloaded circuits (too many devices drawing power).
   • Faulty electrical appliances or equipment.
3. ෆියුස් ප්රතිස්ථාපනය කරන්න: Only after the cause has been identified and corrected, replace the blown fuse with a new Littelfuse FLM3-2/10 FLM3.20 fuse of the identical rating.
4. Repeated Blowing: If the new fuse blows immediately or shortly after replacement, it indicates that the underlying problem has not been resolved. Disconnect power and seek professional assistance.
