    Abstract: A control system may include a processor that may receive a first dataset associated with a current received at a load device coupled to a relay device. The processor may also determine harmonics data associated with the current and determine a switching profile to control moving a first armature of three armatures in the relay device based on the harmonics data. The switching profile is configured to control movement of the first armature between a first position and a second position, and wherein the switching profile comprises a firing angle for moving the first armature with respect to an electrical waveform, a second armature, and a third armature. The processor may then control a current provided to a relay coil of the relay device based on the switching profile, such that the relay coil causes the first armature to move.

    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 relay device that includes armatures associated with phases of voltage signals. The system may also include relay coils, such that each relay coil may receive a respective voltage that magnetizes a respective relay coil, thereby causing the respective armature to move from a respective first position to a respective second position. The system may also include a control system that receive an indication that a fault condition is present, identify a first phase of the phases of voltage signals that is expected to be the next phase of the phases to cross zero, and send a signal to the relay device in response to identifying the first phase. The signal is configured to cause a first relay coil of the relay coils to energize or deenergize.
