At 230 V, the rating is 1 hp. These values define the signal-level switching capability for control circuits and feedback loops. For fine-stranded conductors, the auxiliary terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). Main contact tightening torque is 16 to 8 Nm. The arcing time is 10 to 10 ms, with a 0.25 s arcing time at 50 Hz. This flexibility suits tight enclosures or angled backplanes. The Size S0 footprint is common across the SIRIUS 3RT2 series, simplifying panel layout and spare part stocking.","metaTitle":"Siemens 3RT2023-1AB00 SIRIUS Power Contactor, Size S0","metaDescription":"Siemens 3RT2023-1AB00 SIRIUS power contactor, Size S0, 45 mm width, screw-type coil terminals, 10 million mechanical cycles.
