Door CouplingsMotor starter protectors with a rotary operating mechanism can be mounted in a control cabinet and operated externally by means of a door-coupling rotary operating mechanism. When the cabinet door with motor starter protector is closed, the operating mechanism is coupled. When the motor starter protector closes, the coupling is locked which prevents the door from being opened unintentionally. This interlock can be defeated by the maintenance personnel. In the OPEN position, the rotary operating mechanism can be secured against reclosing with up to 3 padlocks. Inadvertent opening of the door is not possible in this case either### Siemens Sirius 系列接触器和控制继电器Siemens 控制装置，用于高达 5.5kW 的供电装置。 设备的互补特性允许如发动机和换向器的快速简单装配。 相同功率额定值的接触器、过载、断路器和附件间的完美匹配提供了统一的面板外观，标准宽度，并排安装时不降低额定值，节省了空间。

门联轴器

电动机起动器保护器带旋转操作机制，可安装在控制柜中，可从外部通过门联轴器旋转操作机制操作。带有电动机起动器保护器的机柜门关闭时，该工作机制耦合。电动机起动器保护器关闭时，该耦合被锁定，可防止门被意外打开。此互锁可被维护人员解除。在“打开”位置，旋转操作机制可通过 3 个挂锁锁死，以防再次关闭。在这种情况下门不可能被意外打开
