Product details

Siemens SIRIUS 3RT2035-1NB34-3MA0 — Power Contactor, Size S2

The coil accepts 20 to 33 V, with an inrush current peak of 3 A and holding current that drops from 6 A at 24 V to 0.3 A at 220 V. Coil terminals are screw-type, accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire. Switching rates vary by duty: 1,200 cycles/hour at AC-1 maximum, 750 at AC-2, 1,000 at AC-3, and 300 at AC-4.

Dimensions are 55 mm wide, 114 mm high, and 174 mm deep. The contactor can be mounted on a vertical surface with +/-180° rotation and +/-22.5° forward/backward tilt. Clearance requirements: 10 mm upward, downward, and forward; 6 mm at the sides.
