Product details

The 3RF3320-2DA24 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated 20 A in AC-1 duty at 40 °C. 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.
