摘要： A high-voltage direct-current thermal fuse includes one or more fusible components each having two fusible alloy support arms, a fluxing agent, a fusing cavity, two pins, and an insulation block. Two fusible alloy support arms are arranged opposite, and the fusible component is U-shaped. The fusible component and the fluxing agent are sealed within the fusing cavity. The two pins are respectively connected to the two fusible alloy support arms. The insulation block is arranged between the two fusible alloy support arms and separates the two pins. A volume ratio of the fluxing agent to the fusing cavity is approximately 50% or less, preferably, 10%-50%. The number of the one or more fusible components is at least two, and the at least two fusible components are arranged separately. The thermal fuse can avoid the burst and quickly cut off the current, which provides effective thermal protection for a circuit.
