The 3RF3365-3AA45 is a 1-pole SIRIUS 3RF33 solid-state contactor rated 65 A in AC-1 duty at 40 °C, which means it handles resistive heating loads up to that current without derating. The load circuit spans 48-600 V AC, and the control input accepts 4-30 V DC — a wide DC range that covers standard 24 V PLC outputs and allows direct drive from a 5 V logic signal without an interposing relay. Blocking voltage is 1200 V, giving headroom for transient spikes on a 480 V line. The ring cable lug connection is the termination method — expect to land ring terminals on the power studs, not spring cages or screw clamps. That matters for panel wiring: you need the correct lug size and a torque spec from the datasheet.
RoHS compliance is confirmed from January 2024.
Typical deployment is switching resistive loads like heaters in industrial ovens, packaging seal bars, or molding platens where the zero-cross switching of a solid-state contactor eliminates the contact wear and noise of a mechanical relay.
