    • A connect/disconnect mechanism for an MCC unit, prevents a circuit breaker from being turned on while the unit is being inserted into an MCC section, until stabs of the unit have been connected to a power bus. A cam is rotatably mounted on a pivoted platform in the MCC unit, an actuating arm is coupled between a unit on/offhandle of the MCC unit and the cam, and a bail is pivotally mounted on the pivoting platform and connected to a switch handle of the breaker. A cam surface in a slot of the cam is configured to engage a pin projecting from the bail, when the pivoted platform is forced in a backward direction to connect the stabs to the bus, thereby operatively connecting the unit on/off handle to the switch handle of the breaker.
    • 用于MCC单元的连接/断开机构可防止断路器在本机插入MCC部分时打开,直到设备的连接器连接到电源总线为止。 凸轮可旋转地安装在MCC单元中的枢转平台上,致动臂联接在MCC单元的单元开/关手柄和凸轮之间,并且吊环枢转地安装在枢转平台上并连接到 断路器。 凸轮的槽中的凸轮表面被构造成接合从吊环突出的销,当枢转平台被迫向后的方向以将刺柱连接到总线时,从而将单元开/关手柄可操作地连接到开关 断路器的手柄。
