    摘要： The subject of the invention is a delayed-action thermal relay especially suitable for starting motors for refrigerator compressors and the like comprising a housing molded of plastic material with a first, a second, and a third electric terminal molded into the housing, a first U-shaped bimetallic strip inserted between the first and third electrical terminals and carrying in intermediate position at the base portion of the U-shape a contact element cooperating in normally closed condition with a corresponding contact element carried by a second bimetallic strip connected to the second electrical terminal. There is provided on said respective bimetallic strips associated permanent magnet and armature means which tend to keep said bimetallic strips and hence the contact elements provided on the strips electrically engaged in a closed circuit position.

    摘要翻译： 本发明的主题是一种延迟动作热继电器，特别适用于起动用于冰箱压缩机的电动机等，其包括由塑料材料模制的壳体，其中第一，第二和第三电端子模制到壳体中，第一U 形双金属条插入在第一和第三电端子之间，并且在U形的基部处承载在中间位置，接触元件在常闭状态下与由第二双金属带携带的对应的接触元件相连接，第二双金属条连接到第二电 终奌站。 在所述相应的双金属条带上提供相关联的永磁体和衔铁装置，其倾向于保持所述双金属条，并且因此设置在条上的接触元件电接合在闭合回路位置。
