The coil draws 0.25 A at 50 Hz, and the auxiliary contact block (1 NO + 1 NC, per the 18...8 designation for main contacts) carries rated currents from 10 A at 24 V down to 0.3 A at 230 V and 0.6 A at 440 V — enough for PLC inputs, pilot lights, and small relay coils in the control circuit. Switching frequency reaches 1,000 cycles per hour under AC-1, AC-2, AC-3, and AC-3e duty, dropping to 300 cycles/h under AC-4 for plugging or inching applications — a realistic limit for conveyor jogging or press indexing where the contactor sees frequent make-break under load. ## Mounting and wiring — DIN rail footprint and spring-clamp wiring Clearances: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side — tight enough for dense S0 rows but check the arc-chamber vent path if you stack multiple contactors side-by-side without a separator. Spring-type terminals accept solid or stranded conductors from 1 to 10 mm², or 2 × (0.5 to 2.5 mm²) for daisy-chaining control wiring. No screw torque to verify — strip to the correct length (typically 10 mm for spring clamps this size) and push in. The arcing time is listed at 10 ms, which is typical for a contactor of this class and means the arc extinguishes fast enough to avoid welding on moderate overloads. ## Thermal limits and lifecycle Mechanical endurance of the contactor typical is 10 million operations — a number that assumes no load on the main poles. Electrical endurance depends on the switching category and load current; the 1,000 cycles/h AC-3 rating gives a practical benchmark for motor-starting duty on a conveyor or pump.","metaTitle":"Siemens 3RT2023-2AF00 SIRIUS Power Contactor, Size S0, Sprin","metaDescription":"Siemens 3RT2023-2AF00 SIRIUS power contactor, Size S0, spring-type terminals, 45 mm wide, 97 mm deep.
