SLA-230-ALA

The ATC Diversified SLA Series is designed to protect 3-phase equipment against PHASE LOSS, UNDER VOLTAGE, and PHASE REVERSAL conditions. SLA Series Style "A" 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. IND. CONT. EQ. 496Y 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. Style "N" Style "E" NOTE: When a phase is lost while the motor is running, a condition known Phase Monitors as regeneration occurs where a voltage is induced into the open phase PROTECTS 3-PHASE EQUIPMENT nearly equal in magnitude to the normal phase-to-phase voltage. However, • Available up to 480 VAC AGAINST: with the exception of lightly loaded motors, enough change is detected by (625 VAC with "E" style) the SLA to provide the required protection when properly adjusted.
