At 690 V it still delivers 7.5 kW, which covers most 400 V and 690 V motor circuits in European and export panels. The auxiliary contact block carries 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for control-circuit interlocking and status feedback. ## Mounting and wiring checklist Side-by-side mounting is permitted — no derating gap needed for the S0 frame in most configurations. Wire sizes: main contacts accept 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²) solid/stranded, or AWG 2x (16–12), 2x (14–10), 1x 8. Auxiliary contacts take 2x (1–2.5 mm²), 2x (2.5–6 mm²), max 2x 10 mm², or AWG 2x (20–16), 2x (18–14), 1x 12. Strip length is standard for screw terminals — no special tooling needed. Compliance: the part carries a substance prohibitance date of 01.07.2006, aligning with RoHS (EU Directive 2002/95/EC). Protection: IP20 on the front (finger-safe), IP00 at the terminals (no protection). The contactor is intended for installation inside an enclosure that provides the final IP rating. ## Coordination and fusing These values apply to the main circuit; the auxiliary circuit is protected by the control-circuit fuse. Storage temperature is wider (not listed here, but typically exceeds the operating range).","metaTitle":"Siemens 3RT1024-1AG24 SIRIUS Power Contactor, 24 VDC, Size S","metaDescription":"Siemens 3RT1024-1AG24 SIRIUS power contactor, 24 VDC coil, Size S0, 45 mm wide, screw terminals.
