Siemens 3RT2016-1BB41-ZW96 SIRIUS Power Contactor
The 24 VDC coil pulls in at 0.8 x rated voltage (19.2 V) and drops out around 0.1 x rated voltage (2.4 V), giving a solid hold-in range for control circuits with some brownout margin. Main contact ratings: 10 A at 24 V DC, 3 A at 400 V AC, and 1 hp at 230 V AC. That covers small motor and resistive loads in control panels. Switching frequency: up to 1,000 cycles/hour for AC-1 (resistive), 750 cycles/hour for AC-3 (motor), and 250 cycles/hour for AC-4 (plugging/reversing). The AC-3e rating matches the AC-3 figure at 750 cycles/hour. Mounts on 35 mm DIN rail per DIN EN 60715, screw or snap-on. The 45 mm width and 73 mm depth fit standard panel spacing; allow 10 mm clearance above and below, 6 mm at the sides for airflow and wiring. Wire range: solid or stranded 0.5 to 4 mm², with two-wire combinations up to 2x 4 mm². Screw terminals are the standard for this size. Operating temperature -25 to +60 °C, storage -55 to +80 °C. The auxiliary switch is built in (Yes on the spec sheet), so you don't need a separate add-on for feedback. Arcing time 10 to 15 ms, DC switching time 7 to 13 ms — fast enough for most interlocking and safety circuits.
Panel Integration Notes
Size S00 contactor, 45 mm wide, 58 mm tall, 73 mm deep. Fits a standard 35 mm DIN rail. Mounting position: ±180° rotation on vertical surfaces, plus ±22.5° tilt forward/backward — flexible for tight enclosures. Wire the coil with 24 VDC nominal; the screw terminals accept up to 4 mm². The auxiliary switch is integrated, so plan one NO/NC feedback pair into your control logic.
