AC-15 is the switching category for electromagnetic loads — solenoids, contactor coils, clutches — where the inrush can be several times the holding current. The 12 A rating means it handles the steady-state current of those loads, not motor starting current. The control circuit accepts 24-230 V AC or 110-230 V AC, with instantaneous switching (no zero-crossing delay), so it fires on the first half-cycle after the control signal arrives. This is a DIN-rail mounted solid-state contactor, sized for control cabinets where you need silent, wear-free switching of AC coils or small transformer loads. The screw terminals accept standard ferruled wiring, and the 1-pole form factor means it switches one phase — common for single-phase control circuits or as a pilot device driving larger contactors. The SIRIUS 3RF33 series sits between the compact 3RF32 and the higher-current 3RF34 frames, so this is the mid-range option for 12 A AC-15 applications. ## Compliance documentation RoHS compliant since 15-Jan-2024. This is typical for electronic assemblies with solder joints; the declaration is available for downstream users who need to pass it along under REACH.","metaTitle":"Siemens 3RF3320-1BA22 SIRIUS 3RF33 Solid-State Contactor, 12","metaDescription":"Siemens 3RF3320-1BA22 SIRIUS 3RF33 solid-state contactor, 1-pole, 12 A AC-15 at 40 °C, 24-230 V / 110-230 V AC control, screw terminals.

For a lower current, the 3RF3315-1BA22 (8 A) or for higher, the 3RF3330-1BA22 (20 A) are the same form factor and terminal style. No pin-compatible drop-in exists with a different control voltage type (DC control would be a different order code)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RF3320-1BA22","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RF3320-1BA22 when reusing this data.
