A thermal cutoff includes a first fusible element, a second fusible element, and a closed cavity bounded by a housing having an open end, a cover plate, and a sealant. The two ends of the first fusible element and the two ends of the second fusible element are connected in parallel to a first electrode and a second electrode, respectively. The first fusible element and the second fusible element are provided in the closed cavity. A direction extending from a closed end to the open end of the housing is defined as a vertical direction. The first fusible element and the second fusible element are vertically arranged. The thermal cutoff has a vertical configuration and thus in its entirety has an elongated shape to meet corresponding application requirements.
