Phase sequence relay abb.

Sqz3 phase and sequence relay. Most devices are available with two different terminals. The device offers screw connection technology with 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.

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. Medium voltage products and systems. Types 47 47d 47h undervoltage and phase sequence relay. A wide variety of cost effective three phase monitoring relays are available with specialized functionality.
