Remote control change-over switch for breaker

The invention relates to a remote control change-over switch for a breaker. The remote control change-over switch comprises a phase-changing switch installed on the B-B phase and the C-C phase of a three-phase alternating-current supply, a phase-changing motor, a forward starting button, a reverse starting button, a first relay, a second relay, a power module and a fuse protector. The phase-changing motor is coaxially connected with the phase-changing switch. The remote control change-over switch for the breaker has the advantages that due to the fact that the phase-changing motor is arranged inside a circuit module, the independent phase changing can be carried out through button pressing operation, an original electric phase-changing mode through an isolation phase-changing switch or double contactors is effectively replaced, the size is greatly reduced, and usage and operation are convenient.
