    • At least one embodiment of the invention relates to a tripping apparatus, particularly for circuit breakers, which includes at least one controllable tripping magnet having an armature that is operatively connected to a downstream tripping gear, which engages in a tripping mechanism that acts on the circuit breaker and is coupled to a preloaded spring serving as a force amplifier. According to at least one embodiment of the invention, the tripping mechanism includes a camshaft having a plurality of cam lobes, wherein at least one actuating device is associated with each cam lobe having an offset rotational angle, and wherein, when tripped, at least two actuating processes associated with the respective actuating means take place consecutively, so that the full spring force is transmitted by way of the camshaft to at least one of said actuating means so as to perform the relevant actuating process.
    • 本发明的至少一个实施例涉及一种特别用于断路器的脱扣装置,其包括至少一个可控制的跳闸磁体,其具有可操作地连接到下游跳闸齿轮的电枢,其接合作用在电路上的跳闸机构 断路器并且耦合到用作力放大器的预加载弹簧。 根据本发明的至少一个实施例,跳闸机构包括具有多个凸轮凸角的凸轮轴,其中至少一个致动装置与具有偏置旋转角度的每个凸轮凸角相关联,并且其中当跳闸时,至少两个 与相应的致动装置相关联的致动过程连续进行,使得整个弹簧力通过凸轮轴传递到至少一个所述致动装置,以便执行相关的致动过程。
