The 3RT2017-2AP02 is a Size S00 power contactor from the Siemens SIRIUS family, measuring 45 mm wide by 70 mm high by 73 mm deep. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a +/-180° rotation possible on a vertical surface and +/-22.5° tilt forward or backward — useful when you're squeezing it into a crowded panel and need to orient the coil terminals toward the wiring duct. Clearance spacing: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side — no surprises for a standard S00 layout.
Duty Cycle and Switching Life
This contactor is rated for different switching frequencies depending on the load category: 1,000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). The AC-3e rating also sits at 750/h. Arcing time runs 10 to 15 ms at AC, and the make/break times span 4 to 15 ms. Coil hold-in at 24 VDC nominal draws 0.25 A at both 50 Hz and 60 Hz.
