Overview
Designed to protect 3-phase equipment against phase loss, under voltage and phase reversal conditions. The SLA Series sets the standard for phase monitors. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (pickup). When incorrect phase sequence or phase loss occurs or the 3-phase voltages fall below the drop-out voltage, the relay will de-energize (drop-out). Both Delta and Wye systems may be monitored. In Wye systems, connections to the neutral are not required.
