A new arc model is introduced, which describes the behaviour of a circuit breaker using four constant parameters. Comparison of measurement and calculation shows that the description is relatively exact. By means of this model more information about the arc quenching capability of a circuit breaker can be obtained from switching tests than was possible up to now. Examples are given
