Three phase monitoring relays cm pfs the cm pfs is a three phase monitoring relay that is used to monitor three phase mains for incorrect phase sequence and phase failure. You can choose between the proven screw connection technology double chamber cage connection terminals. 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. A wide variety of cost effective three phase monitoring relays are available with specialized functionality.
