This instruction manual provides essential information for the safe and effective use of Generic 250V Fast Blow Ceramic Tube Fuses. These fuses are designed to protect electrical circuits from overcurrent conditions, preventing damage to appliances and systems. Please read this manual thoroughly before installation and operation.
2. ഉൽപ്പന്നം കഴിഞ്ഞുview
The Generic Fast Blow Ceramic Tube Fuses are available in two primary physical dimensions: 5x20mm and 6x30mm. They are rated for a maximum voltage of 250V and come in a wide range of amperages from 0.1A to 30A. The ceramic construction provides enhanced durability and heat resistance.

2.1 Fuse Identification
Fuses typically have markings on their metal caps. For example, "F1A250V" indicates a 1 Ampere (A) fast-blow fuse rated for 250 Volts (V). The 'A' denotes the current unit, and '1A' is the maximum current tolerance value.
2.2 Fuse Dimensions
- A fuse with a length of 20mm and a diameter of 5mm is referred to as a 5x20mm fuse.
- A fuse with a length of 30mm and a diameter of 6mm is referred to as a 6x30mm fuse.

4. ഇൻസ്റ്റലേഷനും സജ്ജീകരണവും
Fuses are critical safety components. Incorrect installation can lead to electrical hazards or damage to equipment. Always ensure the power supply is disconnected before handling fuses.
4.1 Selecting the Correct Fuse
To determine the appropriate fuse amperage for an appliance, use the following calculation:
Current (A) = Wattage (W) / Voltagഇ (വി)
ഉദാample, for a 500W appliance operating at 220V:
Current = 500W / 220V = 2.27A
In this case, select a fuse with an amperage rating slightly higher than 2.27A, such as a 3A fuse, to allow for normal operation without nuisance blowing, but still provide protection against overcurrents. Always refer to the appliance's manufacturer specifications for recommended fuse ratings.
4.2 Fuse Replacement Procedure
- പവർ വിച്ഛേദിക്കുക: Ensure the electrical appliance or circuit is completely disconnected from the power source.
- Locate Fuse Holder: Identify the fuse holder in the appliance or circuit.
- പൊട്ടിയ ഫ്യൂസ് നീക്കം ചെയ്യുക: Carefully remove the old, blown fuse. A blown fuse typically has a broken filament or a discolored glass tube (though ceramic fuses are opaque).
- പുതിയ ഫ്യൂസ് ഇടുക: Insert a new fuse of the ശരിയാണ് ampകോപവും വോളിയവുംtagഇ റേറ്റിംഗ് into the fuse holder. Ensure it fits securely.
- പവർ പുന ore സ്ഥാപിക്കുക: Once the new fuse is securely in place, restore power to the appliance or circuit.
Warning: Never replace a fuse with one of a higher amperage rating than specified. This can lead to severe damage to the appliance or circuit and create a fire hazard.
5. ഓപ്പറേഷൻ
These fast blow ceramic tube fuses are designed to interrupt the flow of current rapidly when an overcurrent condition occurs. This protects sensitive electronic components and wiring from damage. They operate passively and require no user interaction during normal operation.
6. പരിപാലനം
Fuses are generally maintenance-free components. However, periodic inspection is recommended, especially in critical applications.
- വിഷ്വൽ പരിശോധന: Periodically check fuse holders and fuses for signs of corrosion, overheating (discoloration), or physical damage.
- മാറ്റിസ്ഥാപിക്കൽ: Replace any fuse that shows signs of damage or has blown. Always replace with a fuse of identical specifications.
7. പ്രശ്നപരിഹാരം
7.1 Fuse Blows Immediately After Replacement
If a new fuse blows immediately after installation, it indicates a persistent short circuit or an overload condition in the electrical system or appliance. Do not continue to replace fuses without addressing the underlying issue. Consult a qualified electrician or appliance repair technician.
7.2 Appliance Not Functioning
If an appliance stops working, and you suspect a fuse issue:
- പവർ വിച്ഛേദിക്കുക: Always disconnect the appliance from the power source.
- ഫ്യൂസ് പരിശോധിക്കുക: Locate and inspect the fuse. A blown fuse will typically show a broken internal element.
- ഫ്യൂസ് മാറ്റിസ്ഥാപിക്കുക: If the fuse is blown, replace it with a new one of the correct rating.
- ടെസ്റ്റ്: Reconnect power and test the appliance. If the new fuse blows, there is an internal fault that requires professional attention.
8 സുരക്ഷാ വിവരങ്ങൾ
Always prioritize safety when working with electrical components.
- പവർ വിച്ഛേദിക്കുക: Always ensure power is OFF before inspecting or replacing fuses.
