The AC-1 rating means this contactor is sized for resistive loads — heaters, ovens, lighting banks — where inrush is minimal and the load current stays steady. For motor or inductive loads, you'd derate or step to an AC-3 rated device; the 20 A AC-1 figure is the maximum continuous resistive current the output stage can handle without exceeding its thermal limit. The control circuit accepts 24 V DC or 24-230 V AC without a separate power supply module, which simplifies wiring in mixed-voltage panels. The ring cable lug termination suits permanent, high-vibration connections — not a spring-cage for frequent re-termination. Compliance documentation is in order: RoHS compliant since 15-01-24, and REACH Article 33 disclosure notes lead (CAS 7439-92-1) above 0.1% w/w in the product. No UL or CSA listing appears in the record — verify with your local Siemens rep if a specific agency mark is required for your panel. The 3RF3320-3AA02 is part of the SIRIUS 3RF33 family — a compact, 1-pole solid-state contactor line designed for DIN-rail mounting in control cabinets. The packaging dimensions (105 x 27 x 122 mm) give it a narrow footprint, so it slots into tight rows alongside other SIRIUS devices. The ring cable lug connection expects a screw-terminal interface on the load side; plan for a ferrule or ring terminal in your BOM.","metaTitle":"Siemens 3RF3320-3AA02 SIRIUS solid-state contactor, 1-pole,","metaDescription":"Siemens SIRIUS 3RF33 solid-state contactor, 1-pole, AC-1 rated 20 A at 40 °C, 24-230 V UC.
