Thermal Fuse Function and Application
The Thermal Fuse (Thermal Cutoff, Temperature Fuse) is Axial / Radial / Organic Thermal-Link(OTCO) safety parts that stops the flow of electricity to the motor circuit when a overheats. If the fuse is missing or broken, your motor will not start. The thermal fuse is sensitive to external temperature, and the operating temperature is accurate and stable. Small size, sealed structure. Reliable performance. Low resistance value. One-time action cuts off the current, and the current interruption capacity reaches 250VAC/25A.
The thermal fuse has safety certifications UL(C-UL), VDE,CCC, KTL, PSE and complies with RoHS standards.

The thermal fuse is sensitive to external temperature, and the operating temperature is accurate and stable. Small size, sealed structure. Reliable performance. Low resistance value. One-time action cuts off the current, and the current interruption capacity reaches 250VAC/25A.
A thermal fuse fails when the exhaust temperature exceeds the Thermal fuse rating, that is when the temperature rises above the Set temperature that the fuse is designed to handle.
This can Circuit break occur when a heating element is shorted, a regulating thermostat or thermister fails, or with a partially restricted exhaust vent.
The Thermal Fuse attaches to the blower wheel housing. It must be replaced when there is no longer continuity between the terminals. This is a one-time Thermal Fuse, meaning it cannot be re-set. The replacement part features Same current and temperature characteristics.
Uses of thermal fuses:
Coil products: transformers, motors, chargers Network communication equipment: routers, switches Home appliances: TVs, air conditioners, washing machines Audio-visual equipment: cameras, monitors, DVDs Office equipment: computers, printers, copiers Information electronic products: mobile phones, PDAs.

SET Square TCO Thermal Fuse use Flat iron
A piece of fusible alloy wire is connected between the two pins of the thermal fuse, which is covered by a special transparent resin square shell. Current can flow from one pin to another. When the temperature around the thermal fuse rises to its set operating temperature, its fusible alloy wire melts and shrinks into a spherical shape, and is attached to the ends of the two pins with the help of surface tension and special resin. In this way, the circuit is permanently cut off.
