Thermal Cutoffs are one time fuses that automatically interrupt current when a device reaches its rated cutoff temperature. They help protect equipment from overheating and reduce the risk of fire by providing a reliable, non resettable shutoff. Design and materials - Encapsulated in a durable cylindrical housing for protection against dust and moderate moisture exposure - Available in metal or ceramic body options to suit different environments - Pre attached leads for easy wiring and quick installation - Compact sizes to fit tight spaces in compact appliances and tools Ratings and compatibility - Offered in a range of temperature and current ratings to match your equipment - Suitable for heating elements, motors, transformers, power supplies, and other devices with heat risks - Designed for standard wiring practices and common mounting configurations Performance and safety - Provides a precise, single use trip at the specified temperature - Non resettable; once activated, replacement is required - Consistent action under typical operating conditions to maintain safety margins Installation and maintenance - Install in series with the load to ensure interruption of current when tripping - Ensure solid electrical connections and proper insulation - Replace after any trip event to restore protection Use scenarios - In coffee makers or toasters to shut off if airflow is blocked or the element overheats - In space heaters or hair dryers to prevent overheating and potential fire risk - In battery chargers or cordless tool chargers to protect against overheating during operation Notes - Choose the temperature rating slightly above normal operation but below the device’s critical limit - Confirm environmental suitability and follow local electrical codes during installation
