The AC-15 category per IEC 60947-5-1 covers inductive loads with inrush up to 10× steady current, so this contactor handles the coil-energizing surge of multiple contactors or valves on a single pole. Control voltage spans 24-230 V AC and 24 V DC, making it compatible with both AC and DC control circuits without needing a separate interface relay. ## Switching and termination Switching is instantaneous — no zero-cross or soft-start delay built in, so it closes and opens at whatever point in the AC waveform the control signal arrives. This matters for loads that need immediate response, but also means the contactor sees the full transient stress of switching at peak voltage. Termination is via screw terminals, which suits panel builds where ring or fork lugs are preferred over spring-cage connections.","metaTitle":"Siemens 3RF3365-1BA02 SIRIUS 3RF33 solid-state contactor, 27","metaDescription":"Siemens SIRIUS 3RF33 solid-state contactor, 1-pole, 27.5 A AC-15 at 40 °C, 24-230 V AC / 24 V DC control, instantaneous switching, screw terminals.

The rating is the continuous current capacity under those inductive conditions, not a resistive heating load."},{"question":"What compliance documentation is available for this part?","answer":"The part is RoHS compliant since 15 January 2024.
