    • A circuit breaker includes a short-circuit release and a thermal overload release. In at least one embodiment, the short-circuit release includes an armature and a pole which are disposed within a coil former, as well as a yoke plate and a terminal connection which are disposed around the coil former. The thermal overload release includes a metal strip made of at least two types of metal, around which a PTC thermistor is wound, wherein an electric insulator is disposed between PTC thermistor and metal strip. In at least one embodiment, the connection between the thermal overload release and the yoke plate is made by way of a separate bracket.
    • 断路器包括短路释放和热过载释放。 在至少一个实施例中,短路释放包括设置在线圈架内的电枢和极,以及围绕线圈架设置的轭板和端子连接。 热过载释放包括由至少两种类型的金属制成的金属带,PTC热敏电阻围绕其缠绕,其中电绝缘体设置在PTC热敏电阻和金属带之间。 在至少一个实施例中,热过载释放和轭板之间的连接是通过单独的支架进行的。
