The coil draws 0.25 A at 50 Hz and 0.28 A at 60 Hz, so the control transformer or PLC output must be sized for that inrush and hold current. The contactor is rated for 10 million mechanical operations typical, with a maximum switching rate of 1,000 cycles per hour under AC-3 or AC-3e duty. Side-by-side mounting is permitted, which saves rail space in dense panels. The AC-3 motor-switching rating is the one that governs real motor loads: 23 kW at 400 V means this contactor handles a 3-phase induction motor of that size on a 400 V line. The AC-1 resistive rating would be higher, but for motor duty, the AC-3 figure is the binding constraint. The auxiliary contact block (integrated) is rated 6 A at 24 V, 10 A at 230 V, and 3 A at 400 V — enough for pilot duty on a PLC input or relay coil.","metaTitle":"Siemens 3RT6023-1AL20 SIRIUS Power Contactor, 230 VAC Coil,","metaDescription":"Siemens 3RT6023-1AL20 SIRIUS power contactor, 230 VAC 50/60 Hz coil, S0 size, 45 mm wide, screw terminals, rated for 23 kW at 400 V AC-3.

The 3RT6025-1AL20 carries a higher motor rating (30 kW at 400 V vs 23 kW), so the 3RT6023-1AL20 is a drop-in replacement only if the load is within its lower rating.
