摘要： A medium-voltage switchgear system includes a three-phase circuit breaker having first, second and third single-phase vacuum interrupters connected between respective first, second and third single-phase inputs and first, second and third single-phase outputs. Magnetic actuators are connected to first, second and third single-phase vacuum interrupters, which are configured to receive an interrupt signal and in response, actuate the respective vacuum interrupter connected thereto into an open circuit condition. A controller circuit is connected to each of the first, second and third magnetic actuators and generates an interrupt signal in response to a detected single-phase overcurrent or fault on a single-phase circuit and interrupt that single-phase circuit on which the single-phase overcurrent or fault occurred and maintain power on the remaining two single-phase circuits over which a single-phase overcurrent or fault was not detected.

摘要： Motor control centers have units or bucket assemblies with a spring-loaded front panel attached to a housing of the unit by a laterally extending metallic shaft that allows the front panel to pivot open about a long axis of the shaft. When closed, the bottom of the front panel slidably receives and is in abutting contact with the shaft which provides an electrical ground.

摘要： A system and method for connecting supply power to motor control components includes use of a motor control center subunit with moveable supply power contacts. After a motor control center subunit is secured into a motor control center compartment, the supply power contacts may be advanced to engage supply power buses. For disconnection, the supply power contacts may be retracted and isolated from the buses before physical removal of the subunit.

摘要： Methods and systems for reducing exposure to live parts in a panelboard allow a circuit breaker or other branch electrical device to be safely installed and removed from the panelboard. The methods and systems provide a shutter system that operates in conjunction with the circuit breaker or other branch electrical device to automatically restrict access to the conductors in the panelboard until the circuit breaker is inserted in the panelboard. Specifically, the circuit breaker has one or more insertion keys on its casing that align with and fit into one or more keyed openings in the shutter system. When the circuit breaker is inserted into the panelboard, the insertion keys automatically force open the shutter system to allow the circuit breaker terminals to contact the conductors. Removing the circuit breaker from the panelboard automatically closes the shutter system and prevents fingers or tools from inadvertently accessing the conductors.
摘要翻译：用于减少面板中带电部件暴露的方法和系统允许断路器或其他分支电气装置安全地从电路板安装和移除。这些方法和系统提供一种与断路器或其他分支电气装置一起操作的快门系统，以自动限制对面板板中的导体的访问，直到断路器插入到面板中。具体地说，断路器在其壳体上具有一个或多个插入键，该插入键与快门系统中的一个或多个键控开口对齐并且配合到其中。当断路器插入面板时，插入键自动强制打开快门系统，以允许断路器端子接触导线。从电路板上拆下断路器可自动关闭挡板系统，防止手指或工具无意中接触导体。

摘要： A shutter system for a switchgear compartment includes a moveable shutter translatable between a closed position and an open position. Also included is a pusher operatively coupled to a first side of the moveable shutter and configured to impart a force on the moveable shutter in response to an insertion of an electrical device within the switchgear compartment. Further included is a cam member having a cam shaft operatively coupled to the moveable shutter, the cam shaft having a cam track. Yet further included is a bell crank configured to guide along the cam track and translate the moveable shutter between the closed position and the open position.
