The Siemens SIRIUS 3RT6023-1AQ00 is a power contactor in the S0 frame size, designed for switching motor loads under AC-3 duty up to 690 V and resistive loads under AC-1. It delivers 23 kW at 400 V and 60 °C, making it a fit for 400 V three-phase motor circuits in control panels. Rated for AC-3e at 690 V maximum, the contactor handles the inductive break of squirrel-cage motors. Screw-type terminals on both main and auxiliary/control circuits accept 2x (0.5...1.5 mm²) solid or stranded, or 2x (0.75...2.5 mm²) — common for panel wiring with ferrule or direct termination.
Switching capacity and thermal derating
At 60 °C ambient, the contactor is rated for 13.3 kW at 230 V, 23 kW at 400 V, and 40 kW at 690 V — these are the motor output figures for AC-3 duty. The 690 V insulation voltage (rated value) supports 690 V line-to-line systems common in European industrial networks. Switching frequency varies by duty class: AC-1 and AC-3 maximum 1 000 cycles per hour, AC-4 maximum 300 cycles per hour. The AC-3e maximum is also 1 000 cycles per hour. For high-cycle applications like rapid reversing, stay within the AC-4 limit. Coil consumption at 50 Hz is 0.25 A (likely at 230 V, though the evidence does not specify the voltage for that figure). The contactor draws 6 A at 24 V rated value, 10 A at 230 V, and 3 A at 400 V — these are the switching currents the main contacts handle at those voltages.
Side-by-side mounting is permitted, so multiple contactors can pack tightly on the rail.
Substance prohibitance date of 05/01/2012 indicates RoHS compliance. The SIRIUS series typically carries UL, CSA, and CE approvals.
