Abstract: A solid state circuit interrupter provides structures which can manually move an isolation switch of a pole from the ON state to the OFF state without the use of auxiliary power but that advantageously additionally provides an interlock apparatus that avoids manually moving the isolation switch from the ON state to the OFF state until certain conditions exist. One such condition is to ensure that some action is taken, such as by switching a physical interlock between one state and another state. Such a change in state of the physical interlock might additionally result in a change in state of an electronic interlock that would resist the solid state switch being moved to its ON state while the isolation switch is capable of being manually switched to its OFF state. The physical interlock might additionally resist the isolation switch from being manually switched into its ON state.
