    Abstract: This disclosure describes a hybrid circuit breaker for an industrial automation system. The hybrid circuit breaker may include a mechanical switch and solid-state switches. The hybrid circuit breaker may receive control signals to open and close a current path based on moving a spanner of the mechanical switch. In some cases, moving the spanner of the mechanical switch may generate electrical arcs when the hybrid circuit breaker is conducting electrical current. In such cases, the hybrid circuit breaker may remove the electrical arcs by drawing the electrical arcs to a conductive bar and away from the spanner. Moreover, the hybrid circuit breaker may dissipate the electrical arcs on the conductive bar by opening one or multiple solid-state switches disposed on the conductive bar. In some cases, one or multiple voltage suppressors may receive (e.g., suppress or ground) an electrical power of the electrical arcs when the solid-state switches are opened.

    Abstract: A system may include a switching device. The switching device may include an armature that may move between a first position that electrically couples the armature to a first contact and a second position that electrically couples the armature to a second contact. The switching device may also include a coil that may receive a voltage that magnetizes a core, thereby causing the armature to move from the first position to the second position. The system may also include a control system that may monitor a voltage waveform associated with the coil during an open operation of the switching device.

    Abstract: A system includes an electrical enclosure, an industrial automation component disposed within the electrical enclosure, in which the industrial automation component is configured to receive external power from an external power source to perform an operation, a display configured to maintain presentation of image data in absence of the external power being received by the industrial automation component from the external power source, and a control system communicatively coupled to the industrial automation component and to the display. The control system is configured to perform operations that include receiving an indication that the external power is within a range of a threshold, in which the threshold is associated with an insufficient amount of power for the industrial automation component to operate, identifying an error associated with the industrial automation component in response to receiving the indication, and causing the display to render image data indicative of the error.

    Abstract: A system may include an armature configured to move between a first position that electrically couples the armature to a first contact and a second position that electrically couples the armature to a second contact. The system may also include a coil configured receive a current, such that the current conducting in the coil is configured to magnetize a core. The magnetized core may cause the armature to move from the first position to the second position. The system may also include a control system configured to detect a position of the armature based on an inductance of the coil.
