Coil is 24 VDC with an integrated RC surge suppressor across the coil terminals, so you don't need to add an external snubber for DC switching. ## Frame, mounting, and wiring Size S00 means 45 mm wide, 57.5 mm tall, 114 mm deep. Side-by-side mounting allowed — no derating gap required for a row of these on the rail. Screw terminals accept 2x 0.5 to 1.5 mm² solid, 2x 0.75 to 2.5 mm², or max 2x 0.75 to 4 mm². For the main contacts, AWG 2x 20-16, 2x 18-14, or 1x 12. Same gauge range on the auxiliary contacts. Strip length is standard for screw terminals — lands clean with a ferrule. Motor power ratings: 4.5 kW at 500 V, 5.5 kW at 690 V — that's AC-3 duty (squirrel-cage motors, starting and disconnecting under load). For AC-2 duty (slip-ring motors) at 400 V, rated 4 kW. AC-4 (plugging, inching) at 400 V carries 8.5 A. The auxiliary contact ratings are where the RC suppressor matters: at 24 VDC it switches 10 A, at 60 VDC 2 A, at 110 VDC 1 A, at 220 VDC 0.3 A. The RC element clips the inductive kick on DC coil dropout. Coil closing and holding power is 3.3 W DC, steady-state — no inrush spike to size a power supply around.","metaTitle":"Siemens 3RT1016-1XB43-0VE1 SIRIUS Power Contactor, 24 VDC, S","metaDescription":"Siemens SIRIUS power contactor 3RT1016-1XB43-0VE1, 24 VDC coil, Size S00 frame, screw terminals, IP20, rated 4.5 kW at 500 V / 5.5 kW at 690 V.
