For motor loads, the inrush during start-up can be 5-7x the FLA, so this relay is sized for a motor whose full-load amps stay below 50 A — typically a 15-20 kW induction motor on 400 V three-phase, depending on duty cycle. For resistive loads (heaters, lamps), the 50 A rating is the direct selection number. ## Control voltage flexibility The control input accepts 24-230 VAC or 24 VDC, which covers the two most common PLC and relay logic levels in industrial panels. The 24 VDC option is useful for direct connection to a 24 VDC PLC output card without an interposing relay. The AC range (24-230 V) allows the same part to be used across different line voltages in a facility, reducing spare-part variety. RoHS compliance is documented from 15 January 2024. No UL or CSA listing is stated in the available record, so verify local code acceptance with the project's electrical inspector if the installation requires third-party certification.","metaTitle":"Siemens 3RF3050-1AA02 SIRIUS 3RF30 SSR, 50 A, 24-230 VAC/24","metaDescription":"Siemens 3RF3050-1AA02 SIRIUS 3RF30 solid-state relay, 1-pole, 45 mm, 50 A, 24-230 VAC/24 VDC screw terminal.

The main selection difference is the continuous current rating — the 3RF3050-1AA02 is the 50 A variant. A lower-current sibling (e.g., 25 A or 40 A) would be pin-compatible but would limit the load capacity.
