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

1. പവർ വിച്ഛേദിക്കുക: Ensure that the main power supply to the circuit is completely turned off and locked out, if applicable. Verify with a voltagഇ ടെസ്റ്റർ.
2. ഫ്യൂസ് ഹോൾഡർ തിരിച്ചറിയുക: Locate the fuse holder or circuit board where the fuse is to be installed or replaced.
3. Remove Old Fuse (if applicable): 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) കൂടാതെ വാല്യംtage (250V) ratings for the circuit.
5. പുതിയ ഫ്യൂസ് ഇടുക: 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. സുരക്ഷിത കണക്ഷൻ: Ensure the fuse is securely seated in its holder or properly soldered if it's a permanent through-hole mount.
7. പവർ പുന ore സ്ഥാപിക്കുക: Once the fuse is securely installed, restore power to the circuit.

5 പ്രവർത്തന തത്വം

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. പരിപാലനം

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

• ആനുകാലിക പരിശോധന: 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.
• മാറ്റിസ്ഥാപിക്കൽ: A blown fuse must always be replaced with a new fuse of the exact same type, ampകോപം, ഒപ്പം വാല്യംtage rating (e.g., Littelfuse FLM3-2/10 FLM3.20). Never attempt to repair a blown fuse.

7. പ്രശ്‌നപരിഹാരം

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

1. ഊതപ്പെട്ട ഫ്യൂസ് തിരിച്ചറിയുക: 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. ഫ്യൂസ് മാറ്റിസ്ഥാപിക്കുക: 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. ആവർത്തിച്ചുള്ള ഊതൽ: 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.
