Typical holding power draw is 10.5 VA — that's the steady-state load on the control transformer once the contactor is sealed in. The coil draw at pickup is higher (the inrush to pull the armature in), but the 10.5 VA figure is what the control circuit sees continuously. Make sure your transformer or PLC output can handle the inrush peak; the holding VA is well within a standard 24 VA control transformer's capacity. The coil is designed for screw-terminal connection — two terminals for the control voltage, no polarity on AC. It snaps onto the contactor's magnet system without tools; the contactor stays on the DIN rail. That's the field-service angle: you can swap this coil in the panel without pulling wires from the main power circuit. Size S0 is a common contactor frame in the SIRIUS line (covers motor ratings roughly up to 18.5 kW at 400 V AC-3). If you're replacing a coil on an existing S0 contactor, verify the contactor's own order code — the coil voltage must match the existing control circuit.","metaTitle":"Siemens 3RT6926-5AN21 SIRIUS Magnet Coil, 220 V AC, Size S0","metaDescription":"Siemens 3RT6926-5AN21 SIRIUS magnet coil for size S0 contactors. 220 V AC, 50/60 Hz, 10.5 VA typical holding power.

The 3RT1016-1AN22 is a complete size S00 power contactor, not a coil. The 3RT6926-5AN21 coil is for size S0 contactors. The physical magnet system and mounting differ between S00 and S0 frames.
