That AC-1 rating covers resistive loads — heaters, ovens, lighting banks — where the current waveform stays sinusoidal and inrush is minimal. Load voltage spans 48 to 460 V AC, control voltage is 110-230 V AC. RoHS compliance effective from January 2024. Mounts on DIN rail — the 105 x 27 x 122 mm footprint fits standard 35 mm rail. The spring-loaded terminals mean no screw-terminal torque check during commissioning; strip 8-10 mm, push in, done. Control voltage is 110-230 V AC, so it's a direct fit for panels with a 120 V or 230 V control transformer — no DC power supply needed for the coil.","metaTitle":"Siemens 3RF3320-2AA24 SIRIUS 3RF33 solid-state contactor, 20","metaDescription":"Siemens 3RF3320-2AA24 SIRIUS 3RF33 1-pole solid-state contactor, 20 A AC-1 at 40 °C, 48-460 V load, 110-230 V AC control, spring-loaded terminals.
