That 50 A rating is the AC-1 resistive load current — it handles heater banks, lighting, and transformer primary switching at that level without derating for inrush. For motor loads, you'd size down to the AC-51 or AC-53a rating, but the part's not marketed for that; it's built for resistive and slightly inductive loads where you need silent, arc-free switching. The 22.5 mm width is the standard DIN-rail footprint for this class — it clips onto a top-hat rail (EN 60715) in a control panel and leaves room alongside contactors, overloads, and other SIRIUS modular gear. The screw terminals accept up to 6 mm² wire, so it's a straight swap into a panel where you've already got ring or fork terminals on the load side. No extra heatsink required at the 50 A rating if the ambient stays under 40 °C; above that, you'll want to check the derating curve in the manual. The SIRIUS 3RF3 series is Siemens' current-generation solid-state relay line, so you can quote it into a BOM without worrying about a PCN next quarter. RoHS compliant since January 2024. ## Catalog identifiers Group code R711 and product group 3725 are the internal Siemens cataloging fields — useful if you're cross-referencing against a legacy parts list or a distributor's system that keys on those codes instead of the full MPN.","metaTitle":"Siemens 3RF3150-1AA14 SIRIUS solid-state relay, 50 A, 22.5 m","metaDescription":"Siemens SIRIUS 3RF3150-1AA14 semiconductor relay, 1-pole, 22.5 mm width, rated 50 A at 48-460 V, 24 V AC/DC screw terminal.
