Phase sequence relays are designed to monitor

the correct phase rotation of a three phase

system. Several models are avilable from 50 Hz,

60 Hz, and 400 Hz with voltages up to 575 volts.

High shock relay output and reverse contacts are

also available.

Operation:

The relay remains de-energized when voltage in

the proper phase sequence (A, B, C) is applied,

the relay is energized when voltage with incorrect

sequence (A, C, B) is applied.
