The Siemens SIRIUS 3RT1017-2AK62 is a Size S00 power contactor rated for 8.5 A in AC-4 duty at 400 V — that's the switching current for reversing or inching motor loads, where the contactor makes and breaks the motor's locked-rotor current. The spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire, so no screw torque to verify on the line — just strip and push.
For Type 1 coordination (contactor may need replacement after fault), use a 35 A gL/gG fuse.
The AC-4 rating at 400 V is 8.5 A — this governs switching of motor loads under reversing or inching duty where the contactor breaks locked-rotor current.
Both are Size S00 contactors with the same mounting footprint on 35 mm DIN rail and similar terminal spacing, so mechanical fit is the same. The electrical difference is in the coil and auxiliary contact configuration — the 3RT1016-2AP02 uses a different coil voltage and has an auxiliary contact block, while the 3RT1017-2AK62 has a 24 V DC coil and no built-in auxiliary. If your panel wiring expects a 24 V DC coil and no auxiliary, it drops in without rewiring; otherwise, the coil supply and auxiliary wiring must be checked.
