Phase Failure Relays

WILMAR™ Protective Relays – 1000 Series

Function:

• ANSI/IEEE C37.90-1978

• UL file No. E58048

• CSA file No. LR61158

TERMINAL STRIPS

#6 - 32 SCREWS

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.

/16

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.
