The 3RT1064-2AP36 is a SIRIUS S10 power contactor — the largest frame in the SIRIUS contactor family, sized for heavy motor and resistive loads in a 210 x 145 x 202 mm envelope. Rated coil voltage is 220-240 VAC; the magnet coil terminates via spring-type terminals, which speeds wiring compared to screw-clamp on the control side. Mounting is by screw fixing with a vertical mounting surface, rotatable ±90° and tiltable ±22.5° front-to-back — gives flexibility in tight enclosures.
Switching duty cycles and auxiliary contact capacity
Maximum switching rates vary by duty: 750 operations/hour in AC-1 (resistive), 500/h in AC-3 (motor start/run), 250/h in AC-2 (slip-ring motor), and 130/h in AC-4 (plugging/inching). AC-3e (enhanced) rate matches the standard AC-3 at 500/h. These rates define the thermal load on the contact tips — exceeding them shortens electrical life.
Wiring, clearances, and environmental limits
Minimum clearances to adjacent metal: 10 mm upwards, downwards, and sideways; 20 mm forwards — critical for thermal derating and arc flash spacing. Arcing time is 10-15 ms; pick-up/drop-out times are 40-80 ms on both AC and DC.
