The 3RF3320-3AA04 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated AC-1 at 20 A at 40 °C. That AC-1 rating means it switches resistive loads (heaters, lighting) at that current; for motor or inductive loads you derate to the AC-3 curve. The 48-460 V operating range covers standard three-phase line voltages across most industrial regions, and the 24 V DC control input is common for PLC-driven panels. The ring cable lug connection is a fixed termination — you won't swap it for a screw-clamp version in the field.
RoHS compliant since 15-01-24. Export control: AL N / ECCN 9N9999 — no special license required for most destinations.
