Typical mechanical life is 10,000,000 operations. Main contact terminals accept solid or stranded wire from 1 to 10 mm², and fine-stranded wire 2x (0.5 to 2.5 mm²). The coil uses spring-type terminals for fast wiring without tools. Main contact torque specified at 18 to 8 Nm. ## Breaking Capacity and Load Types The contactor has no integrated auxiliary switch, so any auxiliary contact block must be added separately. DC breaking capacity is rated per voltage: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, and 11 A at 480 V. The 480 V rating is notably higher, suggesting a different DC-1 or DC-3 duty curve at that voltage. At 230 V AC, the contactor is rated for 2 hp motor load. Arcing time is specified at 4 to 16 ms at AC, with a tighter 10 to 10 ms range listed separately. For a BOM freeze or second-source review, the closest peer is the 3RT2024-2BB40, which shares the same S0 frame and 45 mm width but differs in coil voltage and terminal configuration. Verify coil compatibility before substituting.","metaTitle":"Siemens 3RT2024-2AV04 SIRIUS Power Contactor, S0 Frame, 45mm","metaDescription":"Siemens 3RT2024-2AV04 SIRIUS power contactor, size S0, 45 mm width, spring-type coil terminals, rated for AC-3 switching at 1000 cycles/h.
