Littelfuse JTD-15-ID ஃபியூஸ் அறிவுறுத்தல் கையேடு
Comprehensive guide for the installation, operation, and maintenance of the Littelfuse JTD-15-ID fuse.
1. தயாரிப்பு முடிந்துவிட்டதுview
The Littelfuse JTD-15-ID is a 15 Amp, 300 VDC, 600 VAC, current-limiting, dual-element time-delay fuse designed for use in all general-purpose circuits. It features a trip indication mechanism for easy identification of a blown fuse.
This fuse provides superior protection for motors, transformers, solenoids, and other inductive loads, as well as for general-purpose circuits. Its time-delay characteristic allows for temporary overcurrents without nuisance tripping, while its current-limiting capability minimizes damage from high fault currents.

The label clearly shows "Littelfuse", "JTD 15 ID", and "Indicator". A small window on the label reveals the internal element and a "Good" or "Replace" indicator.
2. பாதுகாப்பு தகவல்
எச்சரிக்கை: Electrical shock hazard. Always disconnect power before installing or removing fuses. Only qualified personnel should perform electrical work.
- Ensure the fuse rating (voltage and current) matches the circuit requirements.
- Do not use damaged fuses.
- Always replace a blown fuse with a fuse of the same type and rating.

3. நிறுவல்
The JTD-15-ID fuse is designed for installation into compatible fuse holders or blocks. Ensure the fuse holder is rated for the fuse's voltagமின் மற்றும் தற்போதைய.
- சுற்றுக்கு சக்தியைத் துண்டிக்கவும்: Before beginning installation, ensure that the electrical circuit is completely de-energized at the main power source. Verify with a voltagஇ சோதனையாளர்.
- Identify Fuse Holder: Locate the appropriate fuse holder or fuse block in your electrical panel or equipment.
- ஃபியூஸைச் செருகவும்: Carefully insert the JTD-15-ID fuse into the designated fuse holder. Ensure it is seated firmly and correctly.
- இணைப்பைச் சரிபார்க்கவும்: Confirm that the fuse makes proper electrical contact within the holder.
- Re-energize Circuit: Once the fuse is securely installed, you may re-energize the circuit.

4. Operation and Trip Indication
The Littelfuse JTD-15-ID is a passive component designed to protect electrical circuits from overcurrents. It operates by melting an internal element when current exceeds its rated capacity for a specified duration, thereby opening the circuit and preventing damage to equipment.
Trip Indication: This fuse features a visual trip indicator. When the fuse blows, a small pin or flag will typically pop out or change color in the indicator window, signaling that the fuse has operated and needs replacement. Refer to the fuse label for the specific indicator appearance (e.g., "Good" vs. "Replace" text, or a visible pin).

5. பராமரிப்பு
Fuses are generally maintenance-free components. However, periodic inspection of the fuse and its holder is recommended as part of routine electrical system checks.
- காட்சி ஆய்வு: Regularly check the fuse for any signs of physical damage, such as cracks, discoloration, or corrosion.
- Trip Indicator Check: Observe the trip indicator. If it shows a "tripped" state (e.g., "Replace" visible, or pin extended), the fuse has operated and requires replacement.
- சுத்தம்: Ensure the fuse and its holder are free from dust, dirt, or debris that could impede proper contact or heat dissipation.
6. சரிசெய்தல்
The primary "troubleshooting" for a fuse involves identifying if it has blown and replacing it correctly.
| அறிகுறி | சாத்தியமான காரணம் | செயல் |
|---|---|---|
| Circuit is dead; no power to equipment. | ஊதப்பட்ட உருகி. |
|
| New fuse blows immediately after replacement. | Persistent overcurrent, short circuit, or incorrect fuse rating. |
