Product details

The Siemens 3RT7035-1AF00 is a SIRIUS S2-frame contactor, three-pole, with three normally-open main contacts and screw-type terminals for both the main and auxiliary circuits. Control voltage is AC, with a DC holding power of 0.42 W and a closing surge of 0.78 W.

Side-by-side mounting is permitted with no derating gap, which keeps the panel fill factor tight. The S2 frame dimensions are 115 mm deep, 55 mm wide, and 112 mm high.

Environmental and Protection

Operating temperature range is -10 to +55 °C, storage from -25 to +70 °C. Shock resistance is 15g at 5 ms and 8g at 10 ms sine pulse.

For Type 1 coordination (device may be damaged but no fire/arc risk), the fuse is 125 A. Auxiliary contacts are rated for PLC-level reliability at 17 V, 5 mA.
