SLA-440-ALER产品概述
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 (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.
