The Siemens SIRIUS 3RT1016-1AF05-ZX95 is a size S00 power contactor rated for 10 A at 24 V DC, with screw-type terminals and snap-on mounting onto 35 mm DIN rail per EN 50022. It carries three instantaneous main contacts and is designed for switching motor loads in control panels — the S00 frame keeps the footprint to 45 mm wide by 57.5 mm tall by 114 mm deep, which fits standard panel layouts without crowding adjacent devices.
The 10 A rating at 24 V DC is the continuous current the main contacts carry in DC control circuits — sized for switching solenoids, small DC motors, or resistive loads in a 24 VDC panel. For AC motor duty, the contactor is rated 4.5 kW at 500 V (AC-3) and 5.5 kW at 690 V, meaning it handles standard three-phase induction motors up to those power levels.
Wire sizes for main contacts accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded, plus AWG equivalents 2x (20–16), 2x (18–14), and 1x 12. For type 2 coordination, use a gL/gG fuse rated 20 A; for type 1 coordination, 35 A.
