Siemens 3RF2310-1AA02 is a 1-pole solid-state contactor in the SIRIUS 3RF2 family that switches a single-phase AC load (24–230 V) with a 24 V DC control coil. It carries an AC51 rating of about 10.5 A at 40 °C ambient, suitable for controlling resistive loads within that current range, and uses screw terminals for reliable wiring. The unit has a compact 22.5 mm width, designed to fit neatly in control panels where space is at a premium. The coil input is 24 V DC, while the load side switches 24–230 V AC, and the model denotes a single Form A (Normally Open) contact configuration for straightforward on/off control.
