The Siemens SIRIUS 3RT2027-1AD20-1AA0 is a size S0 power contactor with a 24 VDC coil, rated 10 A at 24 V.
The 10 A rating at 24 V covers the auxiliary contact load for a typical PLC output or relay coil — not a motor power circuit. For motor switching, you'd look at the AC-3 current rating on the main contacts (not listed here, but the S0 frame typically handles up to 12 A AC-3). The 1... 10 mm² solid wire capacity matches standard panel wiring; stranded accepts the same range. Mechanical life of 10 million operations means this contactor outlasts most machines in cyclic duty — conveyor indexing, valve actuation, or packaging line pick-and-place.
Standing position on a horizontal surface. The screw-type coil terminals accept 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) solid or stranded.
