ATC Diversified SLA Series 3-Phase Universal Phase Monitoring Relays - Plug-in Style
The ATC Diversified SLA series is a family of three-phase universal phase monitoring relays, designed to provide cost-effective protection against phase loss, under 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.
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, with the exception of lightly loaded motors, enough change is detected by the SLA to provide the required protection when properly adjusted.
