The invention provides a breaker chassis provided with a position indication device, and solves the problem that a conventional breaker chassis only has an electrical indication function. The breaker chassis comprises a chassis frame, wherein the chassis frame is provided with a screw rod, a handle and a microswitch, and the screw rod is connected with the microswitch through a drive board and a microboard. The breaker chassis further comprises a mechanical indication device; the drive board is connected with a connection board; the connection board is connected with the mechanical indication device through a transmission mechanism; the mechanical indication device has a first state and a second state, in the first state, the mechanical indication device displays a test position during installation, and in the second state, the mechanical indication device is driven by the transmission mechanism to display a work position after a breaker is mounted in place. The mechanical indication device is added, so that a worker can clearly indicate the state of the breaker chassis under a power-off condition and know whether the breaker chassis is pushed in or pushed out in place, and the breaker chassis is applicable to installation and debugging processes and the normal work process of the breaker, and has a wide application range.
