The Siemens 3RF3320-3AA06 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated AC-1 / 20 A at 40 °C with a switching voltage range of 48-600 V and a 24 V DC coil. The AC-1 rating means it's specified for resistive loads up to 20 A — think heaters, lighting banks, or transformer primaries — not motor starts. The 24 V DC control side is standard for PLC-driven panels; the ring cable lug connection suits permanent wiring in a cabinet, not quick-disconnect field terminations.
