Siemens SIRIUS 3RT2016-1QB42 — Coupling Contactor, Size S00
The 45 mm width and 58 mm height fit standard panel layouts; depth is 117 mm. This is a coupling contactor — designed to switch control signals between different voltage systems or to isolate logic-level circuits from power circuits. The 24 VDC coil draws minimal inrush, and the 10 A rated current at 24 V handles typical PLC output loads or small solenoid valves. Switching frequency reaches 1000 cycles/hour at AC-1, 750 at AC-3, and 250 at AC-4 — match the duty cycle to your load type.
Accepts solid or stranded wire: 0.5 to 4 mm² for single conductors, or 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² for dual terminations.
