Thermal Cutoffs are one-time safety devices that open the circuit at a preset temperature to prevent overheating. They provide reliable, rapid protection for electrical and electronic equipment, helping to prevent damage, fire risk, and warranty concerns. Key benefits - Fast, decisive response at the rated temperature to interrupt current before damage occurs - Compact form factor for tight installations - Durable construction with a ceramic or metal body for long life in demanding environments - One-time use: once activated, they cannot be reset and must be replaced - Broad compatibility with appliances, motors, transformers, and power supplies Specifications and compatibility - Available in multiple temperature ratings and physical sizes to fit different assemblies - Common lead configurations and shapes to simplify mounting and wiring - Designed to operate in typical electrical circuits and heating elements Use scenarios - In a coffee maker or hair dryer to shut down when internal temperatures rise - In a power supply or charger to protect transformers, coils, or regulators - In small motors or heating elements in tools and HVAC components to provide a safety cutoff Choosing and installation - Select the rating that matches the maximum allowable temperature of your device - Install in series with the load, following the product's mounting and lead connection guidelines
