Thermal cutoffs and cutouts (TCO) are essential circuit protection devices that respond to temperature induction. These components detect overheating caused by abnormal operations in electrical and electronic products and automatically cut off the circuit to prevent fire hazards. Designed for one-time use, thermal cutoffs activate at a specific fuse temperature and must be replaced after operation.

TCOs are widely utilized in household and industrial applications, including hair dryers, electric irons, rice cookers, electric stoves, transformers, motors, water dispensers, and coffee pots. Their reliable performance ensures safety and protection for a variety of thermal-sensitive systems.
