It's built to handle resistive loads in the AC-51 duty class, carrying 10.5 A per the IEC 60947-4-3 standard, and 7 A under UL 508. The control supply takes 180 to 230 VAC at 50 or 60 Hz, drawing about 15 mA. That zero-point switching means the thyristors turn on when the voltage waveform crosses zero, which keeps electrical noise down and extends heater or lamp life — a real advantage on a production line where you don't want relay chatter tripping a controller. ## Sizing and Selection The headline number here is the AC-51 rating of 10.5 A — that's resistive loads like heaters or incandescent lighting. For motor loads or mixed inductive stuff, you'd need to derate; the UL 508 figure of 7 A gives a more conservative line. The minimum operational current is 500 mA, so it won't reliably switch a tiny pilot light or PLC output without a bleed resistor. Each pole dissipates 10.33 W, so if you're packing several side-by-side on a DIN rail — and it does support side-by-side mounting — you'll want to keep an eye on the ambient temperature. The derating temperature kicks in at 40 °C, meaning above that, the current-carrying capacity drops. In a crowded panel, that's the spec that decides whether you need a gap or a fan. Depth is 96.5 mm, so check your enclosure depth before buttoning up the gland plate. Terminals are screw-type for both the main circuit and the control circuit, accepting solid wire from 1.5 to 6 mm² on the main side and 0.5 to 2.5 mm² on the control side. The pollution degree is 3, which is the usual industrial environment — conductive dust or condensation is expected, so keep it in a rated enclosure.","metaTitle":"Siemens 3RF2410-1AC55 SIRIUS Solid-State Contactor, 10.5 A A","metaDescription":"Siemens 3RF2410-1AC55 SIRIUS solid-state contactor, three-phase controlled, 10.5 A AC-51, 7 A UL 508, zero-point switching, 45 mm wide, current production status.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Solid State Relays"],"specifications":{"Depth":"96.5 mm","Solid":"1x (0.5 ... 2.5 mm²), 2x (0.5 ... 1.0 mm²)","Width":"45 mm","at AC":"2 mA","title":"3RF2410-1AC55","Height":"95 mm","Per Pole":"10.33 W","at 50 Hz":"180 ... 230 V","at 60 Hz":"180 ... 230 V","description":"Solid-state contactor 3-phase 3RF2 AC 51 / 10 A / 40 °C 48-600 V / 230 V AC 3-phase controlled screw terminal Blocking voltage 1200 V","up to 460 V":"3NA3801;
