SLA-120-ASA Datasheet PDF - American Technical Ceramics

●The ATC Diversified SLA Series is designed to protect 3-phase equipment against phase loss, undervoltage, and phase reversal conditions.

●With normal operating voltages applied in the proper ABC sequence, the internal relay will energize. When incorrect phase sequence or phase loss occurs, or the three-phase voltages fall below the drop-out voltages, the relay will de-energize.

●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.
