AC-1 covers resistive loads — heaters, ovens, lighting banks — where the switching current matches the load current without motor inrush. The 48-460 V / 110-230 V AC control voltage range means it accepts standard line-voltage control signals directly, no separate control transformer needed for most panels. ## Deployment context Mounts on standard DIN rail in a control panel. The 1-pole form factor saves rail space compared to electromechanical contactors for resistive loads. Short-circuit-proof with a B-curve miniature circuit breaker, so no separate fuse coordination study needed for the branch circuit — just size the MCB to the load.","metaTitle":"Siemens 3RF3320-2DA24 SIRIUS 3RF33 Solid-State Contactor, 20","metaDescription":"Siemens 3RF3320-2DA24 SIRIUS 3RF33 solid-state contactor, 1-pole, 20 A AC-1 at 40 °C, 48-460 V / 110-230 V AC, spring-loaded terminals.
