What to do if Siemens Switch circuit breaker cannot be closed?

If the Siemens Switch circuit breaker cannot be closed, several factors could be at play. Ensure that the operating handle for the removable part is removed. Check that the removable part is either in the working or test position, not in between. If the spring lacks energy, wait for 10 seconds to allow for motor energy storage, or use manual energy storage. Also, make sure the undervoltage trip is activated and that the door for the HV compartment is securely closed.
