A相、B相、C相三根金属导轨11分别通过配电单元支座2与输入断路器3的A相、B相、C相电路相连接。
在配电单元支座2的内部还内置一电量参数检测电路21，可以支持检测交流电或者直流电的电量参数，在实际使用过程中只需要相应地更换空气断路器的型号就可以适配交流电和直流电。
所述电量参数检测电路21包括：
通讯模块213：对外设计有一通讯接口215，用于接入通讯总线实现与外部的数据通讯。在实际应用中，通讯模块213与具有供电功能的RS485总线进行数据通讯，紧挨在一起的若干个电量参数检测电路可以使用手拉手串联的方式接入总线，总线自动分配各个通讯模块的通讯地址，所以通讯模块213本身不需要任何设置.

在配电单元支座2的底部设计有可以灵活调节供电相位的调相装置，在安装到供电导轨1上之前，只需要上下调节调相按钮就可以在A相、B相、C相之间进行选择。因为如果配电柜的前端是三相交流供电，这样设计可以便于实现配电柜的三相平衡。
如图3所示，本发明实施例所述及的配电单元的安装过程包括以下步骤：
1、将断路器3与配电单元支座2进行连接和固定，断路器3的固定依靠配电单元支座2上的断路器安装导轨216实现，依靠配电单元支座2上面的输入电极与断路器3的输入端口实现电路连接；
