TB02 HCET-A Bimetal Thermal Protection Switch Temperature Control & Cutoff for Heating Pad

TB02 HCET-A is a temperature protection device based on Bimetal Thermostat technology, integrating the dual functions of thermal protection switch and thermal cutoff. By sensing the internal temperature change of the equipment, when the temperature exceeds the preset safety threshold, the device can automatically cut off the circuit, providing reliable overheating protection and precise temperature control for lithium battery packs, motor systems, electric blankets/heating pads and other equipment. Its bimetal structure realizes deformation triggering through the composite of metal layers with different expansion coefficients, which combines the stability of mechanical switching and the response speed of electronic temperature control.

Product feature:
