ATC Diversified Electronics SLA-575-ALE

Relay, Sequence Loss Monitor, 3-Phase, 525-625V, 3A, SLA Series Overview The ATC Diversified SLA Series is designed to protect 3-phase equipment against pahse loss, undervoltage, and phase reversal conditions. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (pick-up). When incorrect phase sequence or phase loss occurs or the three-phase voltages fall below the drop out voltages, the relay will de-energize (drop-out). On models featuring indicators, the LED glows when all line conditions are normal. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are NOT required. For UL Listed units, with field wiring terminals, copper wire with 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, with the exception of lightly loaded motors, enough change is detected by the SLA to provide the required protection when properly adjusted. Features: Available Up to 480 VAC Delta or Wye Systems Fixed, Lock Shaft, or Screwdriver Adjustment Several Enclosure Styles Protects 3-Phase Quipment Against: Phase Loss Undervoltage Phase Reversal Typical Applications: Air Handlers Computer Power Protection Conveyor Drive Water Waste and Sewage Machinery Oil and Gas Pumps Sawmill and Woodpump Machinery Power Substation Automatic Transfer Switching for Monitoring Emergency Power Supplies Irrigation Pumps Lift Station Pumps Robotics Equipment Elevator Drives Commercial/Industrial Air Conditioning and Refrigeration Compressors
