The coil draws 0.36 A at 50 Hz and 0.38 A at 60 Hz; closing power is 0.79 W DC, holding power 0.36 W DC — the low holding power reduces heat in the panel. ## Mounting and Environmental Specs The contactor measures 55 mm wide, 112 mm high, and 115 mm deep — the S2 frame size fits standard 55 mm-wide DIN rail slots. Shock resistance is 15g for 5 ms and 8g for 10 ms sine pulse. ## Protection and Coordination For Type 1 coordination (contactor may need replacement after a fault), the fuse rating jumps to 160 A. Wire sizes accepted: 2x 0.5 to 1.5 mm² solid/stranded, or 2x 0.75 to 2.5 mm² with ferrules.","metaTitle":"Siemens 3RT7037-1AF00 Contactor, Size S2, 3-Pole, 690V AC-3","metaDescription":"Siemens 3RT7037-1AF00 contactor, size S2, 3-pole, 690V AC-3 rated.
