It switches 50 A resistive or lightly inductive loads, with the control circuit accepting either 24-230 V AC/DC or 4-30 V DC on the screw terminals. That dual-range control input means you can drive it from a 24 V PLC output or a higher-voltage pilot circuit without an interposing relay. Rated for 50 A continuous, this SSR handles motor starters, heater banks, and solenoid valve banks in a panel. ## Production status and compliance RoHS compliant since 15 January 2024. No export restrictions apply (AL: N, ECCN: N). ## Integration notes The 45 mm housing is the same width as a 3-pole SIRIUS contactor, so keep that in mind when laying out the DIN rail — it occupies one full unit of the 45 mm grid. No auxiliary contact block is included; add one if you need status feedback.","metaTitle":"Siemens 3RF3050-1AA42 SIRIUS 3RF30 solid-state relay, 50 A","metaDescription":"Active-production Siemens 3RF3050-1AA42 SIRIUS 3RF30 solid-state relay, 1-pole 45 mm, 50 A, 24-230 V / 4-30 V DC screw terminal.
