Crompton 256-PLLU Synchro-Check Paralleling Relay is a device that ensures safe paralleling of electrical sources by performing a synchro-check before connection. It supports both 1PH and 3PH configurations and is designed for a 120V 60Hz PLC control circuit. By verifying synchronization prior to paralleling, it helps prevent out-of-sync connections in 1- and 3-phase electrical systems.
