ATC Diversified SLA Series is 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

• Monitors delta or wye systems
• Monitors up to 480 VAC
• Fixed, lock shaft, or screwdriver adjustment
• Automatic reset with manual option available
• Plug-in or surface mount styles

Applications: For air handlers, computer power protection, conveyor drive, water waste & sewage machinery, oil & gas pumps, sawmill & 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 & refrigeration compressors
