That covers most control and small power circuits without lugging. Rated for 1000 switching cycles per hour in AC-1, AC-2, AC-3, and AC-3e duty — that's continuous motor starting and stopping on conveyors, pumps, or fans without exceeding thermal limits. AC-4 (plugging/inching) is capped at 300 cycles/h, reflecting the higher arc energy during reversing or jogging. Auxiliary contact rating is specified by voltage: 6 A at 24 V, 3 A at 400 V, and 1 hp at 230 V. The 400 V figure (3 A) tells you this contactor handles control-circuit switching in 400 VAC panels, not just 24 VDC logic. Clearance: 10 mm upwards, downwards, and forwards; 6 mm at the sides. That's tight enough for dense DIN-rail layouts but leaves space for heat dissipation. No official successor has been announced because none is needed. The 3RT2023-2AG24 is the current production variant for this S0 frame, spring-terminal contactor.","metaTitle":"Siemens 3RT2023-2AG24 SIRIUS Power Contactor, S0 Frame, 45mm","metaDescription":"Siemens 3RT2023-2AG24 SIRIUS power contactor, S0 frame size, 45 mm width, spring-type terminals, screw and snap-on DIN rail mounting.
