This disclosure describes a hybrid circuit breaker for an industrial automation system. The hybrid circuit breaker may include a breaker switch and a solid-state switching circuit coupled in parallel. Moreover, the hybrid circuit breaker may include a disconnector switch coupled in series with the breaker switch. For example, the solid-state switching circuit may include a number of solid-state devices. A control system may provide control signals to the disconnector switch, the breaker switch, and the solid-state switching circuit to switch on and switch off the hybrid circuit breaker. The hybrid circuit breaker may enable or reduce (e.g., halt) electrical current flow based on receiving the control signals. Operation of the breaker circuit and the solid-state switching circuit that are coupled in parallel may provide reduced heat generation while providing safe switching of the hybrid circuit breaker. Moreover, operation of the disconnector switch may provide galvanic isolation.
