The Siemens 3RF3310-1BA24 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated AC-15 at 6 A at 40 °C with a control supply of 110-230 V AC and a main circuit voltage range of 48-460 V. Switching is instantaneous, and termination is via screw terminals.
The AC-15 rating (6 A at 40 °C) defines its suitability for switching electromagnetic loads — solenoids, contactor coils, and similar inductive control circuits — not resistive heaters or motor power. The 48-460 V main circuit range covers common low-voltage AC control and distribution voltages, while the 110-230 V AC control supply matches standard panel control voltages. Instantaneous switching means no zero-cross turn-on delay, so it can switch loads that require immediate response, but may generate higher inrush stress on the load compared to zero-cross types.
RoHS compliant since 15-01-24. Group code R711, product group 3725.
