Product details

Siemens SIRIUS 3RT1064-2AU36 — Power Contactor, Size S10

It measures 210 mm high by 145 mm wide by 202 mm deep and mounts via screw fixing to a vertical surface, with ±90° rotatability and ±22.5° tilt forward/backward for installation flexibility. The coil connection uses spring-type terminals, while the main power poles accept stranded wire from 70 to 240 mm². Auxiliary contacts are included and rated at 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. Switching frequency varies by duty class: 750 ops/h for AC-1 (resistive), 500 ops/h for AC-3 and AC-3e (standard motor starting), 250 ops/h for AC-2 (slip-ring motors), and 130 ops/h for AC-4 (plugging/inching).

Integration Notes

Mount the contactor on a vertical surface with screw fixing through the 11 mm mounting holes.
