Phase Failure Relays
Function: 47
• ANSI/IEEE C37.90-1978
• UL file No. E58048
• CSA file No. LR61158
Phase failure relays protect motors, equipment and
personnel from damage or injury caused by open
phase, reversed phase sequence, or low voltage in a
three phase system. Models are available for 50 and
60 Hz with voltages up to 575 volts. Motor control
switchboards are a common application.
Operation:
The contacts of the relay will close only when it
senses normal conditions of three phase power at
the proper phase sequence.
The relay contacts will remain in their normally open
position (de-energized) when voltage with incorrect
phase sequence is applied, one or more phases are
open, or at undervoltage condition.

Notes:
1. Remove screw for access to the undervoltage
adjustment.
2. Clockwise rotation of the adjustment
potentiometer will raise the drop-out voltage.
