Abb s cm mps n three phase monitoring relays for rated voltage levels up to 820 v ac and 400 hz offer maximum flexibility and control.
Phase sequence relay abb.
Most devices are available with two different terminals.
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.
