The Siemens 3RT1026-1AL24-ZW96 is a SIRIUS power contactor in the S0 frame size, rated for switching three-phase motor loads up to 11 kW at 690 V AC-3 (cites:,). If you need to switch the motor inching or plugging (AC-4), the current limit is 15.5 A at 400 V (cites:). The front is IP20, so it's touch-safe in an enclosure; the terminals are IP00, meaning the wiring compartment needs to be inside the panel (cites:,).
Main power terminals are screw-type, accepting solid conductors from 2x (0.5 to 1.5 mm²) up to 2x (0.75 to 4 mm²), and stranded from 2x (1 to 2.5 mm²) up to 2x 10 mm² (cites:,). For AWG, that's 2x (16 to 12) solid and 2x (14 to 10) stranded, with a single 8 AWG max (cites:). The auxiliary contact block is rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V (cites:,). If you're coordinating with a motor starter or soft starter, the 35 A fuse is the one to plan for in the bill of materials.
