This restriction is due to the coil of the contactor used.
此限制是由于所使用的接触器的线圈。
The coil and the control loop of the original AC contactor need not any change, the goal of electricity saving and silent running can be reached.
且不需对原交流接触器线圈和控制回路作任何改变，即可达到节电和无声运行的目的。
The utility model relates to an autorotation silent electricity-saving coil, used on the ac contactor in the low-voltage controlling circuit, realizing the silent electricity-saving running.
本实用新型涉及的是一种自转无声节电线圈，用于低压控制电路中的交流接触器上，并实现无声节电运行。
The invention provides a coil unit of electromagnetic contactor and assembling method thereof.
本发明为电磁接触器的线圈单元及其装配方法。
Means need 25a contactor, main contact are three normally open, auxiliary contact is one normally open, control coil voltage is DC 110v, order volume is 20 sets.
表示为25a接触器的主触头为三对常开，辅助触头为一对常开，控制线圈的电压为直流110v，订货数量为20台。
It is big to exchange exactly the contactor work noise again, it is many to consume the electricity, and the coil is easily burnt out.
再就是交流接触器工作噪声大，耗电多，线圈易烧坏等等。
