The Siemens 3RF3310-2AA02 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for AC-1 resistive loads at 10 A at 40 °C. The control supply accepts 24-230 V AC or 24 V DC, and the part terminates via spring-loaded terminals — no screw torque to verify, just strip and insert.
This is a DIN-rail mount device, so it clips onto the standard 35 mm rail inside the enclosure. No tool needed for the connection, which saves time during panel build-out.
