3RT2023-1FB40
This Siemens SIRIUS 3RT2023-1FB40 is a size S0 power contactor that'll handle your motor loads out here in the grease. Coil pulls 24 V DC, and it mounts onto a 35 mm DIN rail with screw or snap-on. Wire from 1 to 10 mm² solid or stranded—plenty for the runs you'll see on a lube skid.
Screw and snap-on onto 35 mm DIN rail per EN 60715. You've got 10 mm clearance up, down, and forward, 6 mm at the sides. Ambient operating range -25 to +60 °C, storage down to -55 °C. So it'll live in a warm panel or a cold warehouse.
