    No. Travel measurements are a very valuable tool in circuit breaker analysis. One of the common arguments against measuring motion on vacuum CBs is that the contact stroke is so short that you are better off measuring stroke with a pair of calipers when the breaker is in fully open position compared to fully closed position and you can verify the CB is traveling fast enough from the contact times.
