What this SSR does on your line
The Siemens 3RF3050-1AA42 is a 1-pole solid-state relay from the SIRIUS 3RF30 family, in the 45 mm width housing. 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.
