Sourcing & Lifecycle — Active Production, No End-of-Life Signal
The 3RT6023-1AP20: Substance compliance is documented: RoHS prohibition date 05/01/2012, so the part meets the EU RoHS directive. Expect a CE declaration and RoHS certificate with the shipment.
What the Ratings Mean — S0 Frame, Motor Power, and Duty
Siemens SIRIUS size S0 contactor. AC-3 rated power at 400 V is 23 kW at 60 °C ambient. AC-3 and AC-3e maximum rated voltage is 690 V, matching the insulation voltage rating of 690 V. Mechanical life typical 10 million operations. Electrical life at AC-3 max is 1,000 operations per hour; at AC-4 it drops to 300 operations per hour.
Panel Fit — DIN Rail Mounting and Screw Terminals
Side-by-side mounting is allowed — no derating gap required between units, though the 60 °C ambient rating already accounts for the heat rise in a dense panel. Dimensions: 45 mm wide, 85 mm high, 97 mm deep. Screw-type terminals for main and auxiliary circuits.
Switching Frequency and Coil Data
Maximum switching frequency at AC is 5,000 operations per hour. For AC-1 and AC-3 the electrical max is 1,000 ops/h; for AC-4 it is 300 ops/h. Auxiliary contact ratings: 6 A at 24 V, 10 A at 230 V, 3 A at 400 V, 1 A at 690 V. These are the thermal current ratings for the built-in auxiliary contacts — enough for signaling a PLC input or driving a small relay directly.
