The Siemens 3RF3365-3AA04 is a 1-pole solid-state contactor from the SIRIUS 3RF33 series, rated for AC-1 resistive loads at 65 A continuous current at 40 °C ambient. That 65 A figure is the continuous carrying capacity for resistive heater or lighting banks — not motor starting, which would need the AC-3 duty rating. The load voltage range spans 48-460 V AC, and the control side runs on 24 V DC, making it a straight swap-in for standard PLC or relay logic outputs.
Connection and mounting
Termination is via ring cable lug — not screw clamp or spring cage. That means you need a crimp tool and ring terminals sized for your wire gauge before you land it on the busbar or contactor rail. The packaging dimensions (105 x 50 x 125 mm) suggest a compact footprint for DIN-rail mounting inside a standard enclosure, though the ring-lug interface takes a bit more panel planning than a push-in terminal.
