SIRIUS Size S00 power contactor — 24 VDC coil, screw terminals
The Siemens SIRIUS 3RT2016-1AR61 is a Size S00 power contactor with a 24 VDC coil terminated via screw-type terminals. It carries an auxiliary switch rated 10 A at 24 V, 2 A at 48 V, and 1 A at 110 V — enough for pilot duty or PLC output isolation in a standard control panel. The main contact rating is 20 to 12 A (likely AC-3 duty, though the evidence does not specify the duty class for that range). Mounting is screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The contactor can be rotated ±180° on a vertical surface and tilted ±22.5° forward/backward — useful when panel layout forces an unconventional orientation. Clearance: 10 mm upward/downward/forward, 6 mm at the sides.
Switching rates and thermal limits
Maximum switching rates: 1,000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting/running), and 250 cycles/hour at AC-4 (plugging/inching). The AC-3e rate matches AC-3 at 750 cycles/hour. These are the mechanical limits; thermal derating applies above 40 °C ambient. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. Wire sizes accepted: solid or stranded 0.5 to 4 mm², with dual-wire capability: 2×(0.5–1.5 mm²), 2×(0.75–2.5 mm²), or 2×4 mm². Arcing time is 10–15 ms at AC; the contactor's mechanical life is typically 30 million operations.
