Rated insulation voltage 690 V and surge voltage resistance 6 kV place it in the standard 690 VAC class for industrial motor switching. ## Coil power and control circuit considerations Closing power is 0.78 W DC holding power, meaning the coil's inrush is brief and the steady-state thermal load on the control transformer is low. The auxiliary contact block (field-installable) is rated for PLC-level reliability at 17 V, 5 mA — dry-switching compatible, so you can feed a 24 VDC PLC input directly without a separate interface relay. This helps when fitting into tight enclosures or angled subpanels. Side-by-side mounting is permitted, so no extra spacing is needed between units on the same rail. ## Fault coordination and auxiliary ratings For type of coordination 2 (no-weld condition), the required backup fuse is gL/gG 80 A; for type 1 coordination (allowable weld), 125 A. The auxiliary contact ratings at 230 V AC are 6 A, at 400 V AC 3 A, and at 690 V AC 1 A. DC-13 switching at 220 V is rated 0.3 A. These numbers define the maximum load the auxiliary contacts can break — useful when driving small contactors or indicator lamps directly.","metaTitle":"Siemens 3RT7035-1AV00 Contactor, S2, 3-Pole, AC Control, 690","metaDescription":"Siemens 3RT7035-1AV00 S2 contactor, 3-pole, 3 NO main contacts, AC coil, 690 V AC-3 max, IP20 front.
