Thermal cutoffs are safety devices used to protect equipment from overheating by interrupting current when a preset temperature is reached. - Function: opens the circuit at the designated temperature to stop heat buildup and reduce the risk of damage or fire. - Compatibility: suitable for appliances, motors, transformers, and other equipment that require thermal protection. Confirm the temperature rating and current rating match your device. - Size and form: compact units designed to fit in tight spaces. Dimensions and ratings vary by model, so check the exact measurements for your application. - Material and construction: built with a durable housing and leads for reliable integration into electrical assemblies. - Performance: designed to deliver a consistent trip temperature within specified tolerances, providing dependable protection over the device life. - Applications and use scenarios: - In household hair dryers or irons to prevent overheating and potential damage. - In power supplies, chargers, and small transformers to shut down if internal temperatures rise. - In compact kitchen or personal care appliances such as coffee makers to protect internal components during normal use. - How to select: choose a cutoff temperature that matches your device’s maximum operating temperature and a current rating appropriate for the circuit. Ensure proper mounting and insulation, and replace the unit after it has tripped.
