The SLA Series Three-Phase Monitoring Relay from ATC Diversified Electronics is designed to provide cost-effective protection against from phase loss, voltage, and phase reversal conditions that can contribute to premature motor or equipment failure and downtime. It is designed for use with three-phase systems (Delta and Wye), such as those typically found in motor control centers or other critical motor and pump monitoring applications. For UL Listed units, with field wiring terminals, copper wire with a 60°/75°C rating must be used for control circuitry connections. NOTE: When a phase is lost while the motor is running, a condition known as regeneration occurs where a voltage is induced into the open phase nearly equal in magnitude to the normal phase-to-phase voltage. However, except for lightly loaded motors, enough change is detected by the SLA to provide the required protection when properly adjusted.
