Thermal Cutoffs (TCO)

Thermal cutoffs (TCOs) are a type of circuit protection device that is used to protect electronic circuits from overheating. A TCO is a temperature-sensitive switch that is typically mounted on a circuit board or other heat-generating component. When the temperature of the component exceeds a certain threshold, the TCO will open, breaking the circuit and preventing further heating. Once the temperature has cooled down, the TCO will automatically reset and allow the circuit to resume operation. TCOs are often used in conjunction with other types of circuit protection devices, such as fuses and thermal fuses, to provide a robust and effective protection against overheating.
