  If your Siemens Industrial Equipment breaker will not close electrically, but the ready-to-close indicator is OK, consider the following: * The operating voltage of the stored-energy activation solenoid might be incorrect or unavailable: Check or apply the correct voltage. * The circuit-breaker may be in the disconnected position in the guide frame: Crank the circuit-breaker into the test or connected position. * The auxiliary circuit plug may be taken out: Plug in the auxiliary circuit plug.

  Dana SantiagoAug 9, 2025
  If the Siemens Industrial Equipment breaker cannot be moved from the maintenance position to the disconnected position, consider these causes: 1. The racing-in mechanism of the breaker is not in the disconnected position: Crank the mechanism into the disconnected position. 2. An attempt was made to fit a breaker with a different rated current in the guide frame: Only insert a circuit-breaker with the same rated current data as the guide frames. 3. The coding of the breaker and guide frame do not match: Only insert circuit-breaker with the same rated current data as the guide frames.

What causes resistance when cranking Siemens Industrial Equipment from disconnected to test?

  If you feel strong resistance immediately after leaving the disconnected position when cranking your Siemens Industrial Equipment from the disconnected into the test position, it may be because the breaker is not pushed right in, and the lateral latches are not yet engaged. Push the breaker as far as the stop into the disconnected position until the latches at the side engage.
