Thermal Cutoffs, Cutouts (TCO) are safety devices designed to prevent electrical appliances and circuits from overheating and causing fire hazards. These components function by interrupting the flow of electricity when they detect temperatures exceeding safe limits. The main function of a TCO is to provide reliable and automatic temperature control to ensure the safety of electronic equipment by cutting off the power in the event of a temperature rise beyond a predetermined threshold.
TCOs are commonly used in a variety of household and industrial appliances, including coffee makers, hair dryers, and HVAC systems, where preventing overheating is critical. They are valued for their simplicity, cost-effectiveness, and reliable performance under critical conditions. Notable manufacturers of Thermal Cutoffs, Cutouts include companies like Schott, Panasonic, and Elmwood.
