Phase sequence monitoring a change of the phase sequence during operation or an incorrect phase sequence that is applied at start up will cause a three phase motor to run with reverse rotation. All three phase monitoring relays of the abb cm range detect a phase loss as soon as the voltage of one phase drops below 60 of its nominal value. All devices are available with two different terminal versions.
