Mini-Breakers are Thermal Cutoff (TCO) devices which are used as safety devices to help prevent heat and fires caused by excess current, mainly in lithium-ion batteries. Used in batteries for such devices as notebook PCs, tablets, digital cameras, and smartphones, our Mini-Breakers are self-preserving devices designed to stay tripped (operated) during abnormal temperatures, and then recover when power is cut and the temperature returns to a safe level. This allows for protection at lower temperatures compared with polymer PTCs and temperature fuses used for the same applications.
