The Phase Sequence category at Roshanex lists phase sequence relays that protect three-phase motors and equipment. It currently features two ABB monitoring relays.

The ABB CM-PFS.S checks phase sequence and phase failure, so it helps prevent reverse motor rotation. The CM-PVS.41S adds under and over voltage monitoring as well. When a fault appears, these relays switch off the control circuit before damage occurs.

Panel builders and maintenance teams fit them on pumps, compressors, lifts and HVAC plants. If you need help choosing a model, contact our team, and we will deliver across Pakistan.
