The Siemens 3RF3310-1AA06 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for AC-1 resistive loads at 10 A and 40 °C ambient, with a switching voltage range of 48-600 V and a 24 V DC control input via screw terminals. The AC-1 rating means it is designed for resistive or slightly inductive loads — heaters, incandescent lamps, or resistive banks — where inrush current is minimal. For motor or transformer loads (AC-3/AC-4), derate or select a higher-rated variant.
Screw terminals simplify wiring in a control panel — accept stranded or solid conductors without special tooling. The 97 x 27 x 105 mm package fits standard DIN-rail mounting; the 27 mm width occupies roughly 1.5 standard 17.5 mm modular device slots. The 24 V DC control side draws minimal current from the PLC or PSU — typical solid-state contactor coil draw is under 50 mA, so it won't strain a 24 VDC bus shared with other loads.
