The PRA-100 Series Phase Sequence Monitors are designed to allow

the output to energize only when the phase connections are in the

proper sequence. For use in applications where motor direction is

critical or the installation is required by code to have sequence detec-

tion.

When the phase sequence is correct and the operating voltage is

present on all phases, the relay will energize and the green LED

indicator will glow. If the phases are in reverse rotation, the relay will

not energize and the red LED indicator will glow. The PRA-100 Series

will not detect phase loss while the motor is turning. The PRA Series is

UL Listed under UL File Number E55826.
