The 10 A AC-12 rating means this contactor handles resistive loads up to that current in control circuits — typical for switching heaters, lamps, or transformer primaries. For motor loads, the AC-2 rating at 400 V is 5.5 kW, and AC-4 at 400 V is 12.5 A, covering reversing or plugging duty cycles. The S0 frame takes 45 mm width on the rail, with side-by-side mounting permitted — no derating gap needed for adjacent units. Wire range for main contacts: solid/stranded 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²). AWG equivalents: 2x (16–12), 2x (14–10), 1x 8. Strip length and ferrule sizing follow standard Siemens practice for screw terminals. This lets the panel designer balance protection level against fuse size and selectivity with upstream devices.","metaTitle":"Siemens 3RT1024-1AF04 SIRIUS Power Contactor, S0, 24 VDC, 10","metaDescription":"Siemens 3RT1024-1AF04 SIRIUS power contactor, S0 frame, 3-pole, 24 VDC coil, 10 A rated operational current at AC-12.
