  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.

  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.

  If the guide rails of your Siemens Industrial Equipment cannot be pulled out for fitting a circuit-breaker, it might be because the shutter is locked with one or two padlocks. Remove the padlocks to resolve this issue.

What causes resistance when cranking Siemens Industrial Equipment from disconnected to test?
- J
  John CruzSep 4, 2025
  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.

  If the Siemens Industrial Equipment breaker cannot be closed mechanically or electrically, and the ready-to-close indicator is on, consider these potential causes: 1. The spring may not be charged: Charge the spring. 2. The undervoltage release may not be excited: Energize the undervoltage release. 3. The mechanical reclosing lock-out may be effective: Rectify the cause of overcurrent tripping and press RESET. 4. The electrical closing interlock may be effective: Shut off control voltage for interlocking. 5. The mechanical OFF push-button may be blocked off: Clear the pushbutton. 6. Lockout against closing with switchgear cabinet door open effective: Close switch gear cabinet door. 7. Mutual mechanical breaker interlocks effective: Open second breaker or crank into disconnected pos...
