Can 9065 Solidstate overload relays be used in single phase applications?
NEMA Contactors and Overload relays
9065 solid state relays series F
Older MotorLogic solid state overload relays could not be used with single phase applications, but series F units can.
Yes, however only Series F and newer. These units can be used with single phase applications by looping one of the wires so that it passes through all three CTs in the overload. See page 8 of the attached instruction sheet for an example.
