The coil pickup is guaranteed at 85% of rated voltage (20.4 V DC) and the dropout threshold sits at 1.1× rated (26.4 V DC), giving a clean operate/release margin for PLC-driven outputs. The vertical mounting surface allows ±180° rotation and ±30° tilt front-to-back, so panel layout options are flexible within the enclosure. ## Switching Ratings and Duty DC switching capability is specified across the voltage range: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 0.8 A at 440 V. For AC loads at 230 V it handles 6 A, and at 400 V it handles 3 A. The auxiliary contacts are rated 9 A per NC or NO contact, with a 16 A rating at 24 V DC per contact. Arcing time runs 10–15 ms, and operate time at DC is 7–10 ms — relevant for coordinating with downstream contactors or safety relays in a sequence. Screw-type terminals on both main and control circuits accept solid or stranded conductors: 2× (0.5–1.5 mm²), 2× (0.75–2.5 mm²), and max 2× (0.75–4 mm²). For AWG, main contacts accept 2× (20–16), 2× (18–14), or 1× 12.","metaTitle":"Siemens 3RT1516-1BB40 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1516-1BB40 power contactor, size S00, 24 VDC coil, screw terminals.
