A polyphase metal-enclosed, gas-insulated high-voltage circuit breaker and a switchgear including the circuit breaker is provided. According to the invention, the resolution of the depth images is increased by using the image data of the main image. The implantation depth controlling element can comprise an inner and an outer cylinder, such as where the outer cylinder has interior threads, and the inner cylinder has exterior threads. The first part and the mechanism are connected to one another such that the first part actuates the mechanism between its positions in response to the first part moving between the closed and opened positions. If desired, the state machine may then use one or more other signals, such as signals from a user or from the process, to transition between a set of different states used to safely return the process plant back to the normal operating state from the tripped or safe state. The third filter is connected in parallel with a third pass-through line, wherein the first output switch is connected to the second input switch and the second output switch is connected to the third input switch.
