The BH-TB02B series thermal protector is a thermal protection device with an ultra-small size (L13.5 x W 5.5 x H 2.5mm) that is highly sensitive to both current and temperature. It is connected in series in the protected circuit. When temperature and/or current increases, the heat generated is transferred to the bimetal element inside the thermal protector. When the preset operating temperature is reached, the bimetal element quickly activates, disconnecting the internal contacts and thus cutting off the power supply circuit. When the temperature of the protected circuit drops to the rated reset temperature, the bimetallic element returns to its initial state, the internal contacts close, and the protected circuit conducts again. The BH-TB02B series thermal protectors are used in lithium batteries, small motors, ballasts, transformers, electromagnetic switches, electric heating devices, portable power tools, and other electrical equipment.
