Thermal Cutoffs A one time safety fuse that automatically opens the circuit when the device temperature reaches its rated trip point. It permanently interrupts power to prevent overheating and potential damage. Key benefits - Provides reliable overheat protection to reduce fire risk and equipment damage - Responds quickly to high temperature to prevent failures - Easy to install with standard leads and simple wiring - Durable metal body and sealed internal components designed for long term use - Available in multiple temperature ratings and sizes to fit different devices Function and performance - Non resettable fuse that activates at a specified trip temperature - Delivers precise, predictable protection with fast response - Maintains safety performance under normal operating conditions Compatibility and form factor - Suitable for appliances, heating equipment, motors, transformers and power supplies - Available in various sizes and lead configurations to match device specs - Choose according to model temperature rating, size and mounting needs Size and materials - Compact cylindrical metal housing with insulated leads - Internal components sealed for reliability - Built to withstand typical thermal and environmental conditions in household and industrial applications Use scenarios - In a coffee maker or kettle to cut power if overheating - In a hair dryer or space heater to prevent excessive temperature rise - In a power supply or 3D printer hot end to guard against thermal runaway How to choose - Verify the trip temperature, form factor, lead length, and mounting method against the device specification to ensure proper fit and protection
