The Siemens 3RF3310-3AA04 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for 10 A in AC-1 (resistive) duty at 40 °C ambient. The control side runs on 24 V DC, so it drops straight into a standard PLC output or relay circuit without an extra power supply. Supply voltage range is 48-460 V AC, covering most single-phase line voltages across global plants.
This contactor uses ring cable lug connections — expect to crimp ring terminals rather than push ferrules into a spring cage. The packaging dimensions (97 x 27 x 105 mm) mean it takes a single 27 mm wide DIN-rail slot, so it fits in a crowded enclosure without forcing a wider panel. No auxiliary contact block is mentioned in the listing; if you need feedback to the PLC, plan for a separate monitoring relay or a different variant.
