DESCRIPTION
The Model 153 Reverse Phase Relay is designed to
continuously monitor phase rotation of 3-phase lines.
This device should be used in applications where proper
phase rotation is critical, such as fan motors,
compressors, grinders, elevators, etc.
The solid-state sensing circuit drives an internal
electromechanical relay which energizes when power,
with correct phase rotation, is applied.
The relay will not energize if the applied phases are
reversed. It will de-energize if phase rotation is reversed
while the motor is running. An LED indicator will
illuminate with correct ABC phase rotation.
