2 സുരക്ഷാ വിവരങ്ങൾ

മുന്നറിയിപ്പ്: Electrical shock hazard. Always disconnect power before installing, removing, or inspecting fuses. Failure to do so may result in serious injury or death.

3. ഇൻസ്റ്റലേഷൻ (സജ്ജീകരണം)

The NLS30 fuse is designed for surface mounting within appropriate fuse holders or blocks. Follow these general steps for installation:

  1. പവർ വിച്ഛേദിക്കുക: Locate the main power source for the circuit where the fuse will be installed or replaced and turn it OFF. Verify power is off using a voltagഇ ടെസ്റ്റർ.
  2. ഫ്യൂസ് ഹോൾഡർ തിരിച്ചറിയുക: Locate the fuse holder or block designed for Class K5 fuses.
  3. ഫ്യൂസ് ചേർക്കുക: Carefully insert the NLS30 fuse into the designated fuse clips or holder. Ensure a secure and proper connection.
  4. പവർ പുന ore സ്ഥാപിക്കുക: Once the fuse is securely in place and all connections are verified, restore power to the circuit.

Note: Always refer to the specific equipment's wiring diagrams and instructions for detailed fuse placement and installation procedures.

4. ഓപ്പറേഷൻ

The Littelfuse NLS30 is a passive, fast-acting protective device. It operates by interrupting the flow of current in a circuit when an overcurrent condition (e.g., short circuit or overload) occurs. When the current exceeds the fuse's 30 Amp rating, the internal element melts, opening the circuit and preventing damage to electrical components or wiring.

As a "one-time" fuse, the NLS30 must be replaced after it has operated (blown) to restore power to the circuit.

5. പരിപാലനം

The NLS30 fuse requires no routine maintenance. Its function is to provide overcurrent protection and then be replaced once it has performed its duty.

6. പ്രശ്‌നപരിഹാരം

If a circuit protected by an NLS30 fuse loses power, the fuse may have blown due to an overcurrent condition. Follow these steps:

  1. പവർ വിച്ഛേദിക്കുക: Turn off all power to the affected circuit at the main breaker or disconnect switch.
  2. ഊതപ്പെട്ട ഫ്യൂസ് തിരിച്ചറിയുക: Visually inspect the NLS30 fuse. While this fuse type may not have a clear indicator, a blown fuse often shows signs of discoloration or a broken internal element if visible. A multimeter can be used to test for continuity across the fuse.
  3. കാരണം തിരിച്ചറിയുക: Before replacing the fuse, investigate the cause of the overcurrent. This could be a short circuit, an overloaded appliance, or faulty wiring. Address the underlying issue to prevent immediate re-blowing of the new fuse.
  4. ഫ്യൂസ് മാറ്റിസ്ഥാപിക്കുക: Once the cause is identified and rectified, replace the blown NLS30 fuse with a new one of the identical rating. Refer to the "Installation" section for proper replacement steps.
  5. പവർ പുന ore സ്ഥാപിക്കുക: Restore power to the circuit and verify proper operation.

If the new fuse blows immediately, do not continue to replace it. Consult a qualified electrician to diagnose and repair the electrical issue.
