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.

Consult factory for additional models and options

Notes:

1. Remove screw for access to the undervoltage

adjustment.

2. Clockwise rotation of the adjustment

potentiometer will raise the drop-out voltage.
