Choose a single phasing preventer
A single phasing preventer (phase failure relay) switches off the motor starter when a phase is lost or the three voltages become unbalanced, before the motor overheats. Choose by supply voltage, whether you also want under/over-voltage protection, the number of output contacts and the mounting.
