Product Description（产品描述）

The UCHIHASHI T3F Thermal Fuse (Temperature Cutoff) is a high-performance safety component designed to protect electrical appliances from overheating and fire hazards. When the operating temperature reaches 115°C, the fuse will permanently open the circuit to stop power flow, ensuring reliable protection for equipment and users.

With a rating of AC250V / 2A, the T3F series is suitable for various household appliances and industrial devices. Backed by multiple certifications including UL, PSE, KTL, and VDE, it is a trusted solution for export products and safety-critical designs.

Additionally, this thermal fuse complies with RoHS and REACH, making it an environmentally friendly choice for modern electronics manufacturing.

🔧 Applications（适用范围）

Electric motors / Motor windings
Transformers / Power transformers
Power adapters & chargers
Household appliances (fan, heater, coffee machine, etc.)
Industrial control equipment
Electrical heating devices

⚠ Installation Notes / Important Precautions（安装注意事项）

1. Do NOT solder directly on the thermal fuse

Direct soldering may cause premature activation or damage due to heat. Always use proper connection methods such as crimp terminals or recommended welding techniques.

2. Avoid excessive clamping force

When fixing the fuse, do not apply strong mechanical pressure. Excessive force may deform the body and affect its performance.

3. Keep correct thermal contact

Install the fuse in close contact with the protected component (motor winding, transformer core, etc.) to ensure accurate temperature sensing and reliable protection.

4. Prevent bending near the fuse body

Avoid bending leads too close to the fuse body. Maintain a safe bending distance to prevent internal structure damage.

5. Do not exceed rated voltage/current

Ensure the circuit load does not exceed AC250V / 2A. Overloading may lead to abnormal heating and reduced safety.

6. Keep away from moisture and corrosive environment

Store and use in dry conditions. Avoid exposure to oil, chemicals, or corrosive gases to maintain stable insulation and long-term reliability.

7. One-time protection device

This thermal fuse is a non-resettable safety component. Once activated, it must be replaced with the same specification.
