Phase Sequence Relays WILMAR™ Protective Relays – 900 Series Function: 47 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. 3 5/32 2 3/4 1 3 /4 6 5 /1 2 2 1/8 6 11/1 2 PART NUMBER SELECTION 6 - 32 x 3/8 studs 4 places Note: Dimensions in inches.
