Thermal cut-off
thermal fuse and circuit breaker cutoff temperature
They are the same in that they can achieve short circuit protection. The principle of a thermal fuse is to use a current flowing through a conductor to cause the conductor to heat up. When the melting point of the conductor is reached, the conductor is melted so that the circuit-protected electrical appliances and lines are not burned.
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.
Thermal Safety thermostat & Thermal cut-off switch For Electric Heater
China Custom Thermal cut-off switch 2A~60A 30-150C (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint “plink” sound) and re-closes when the temperature drops. Thermal switches play a critical role in temperature monitoring, serving to shut down systems when Heat Convector, Room Heater their operating temperature exceeds a safe level.
