This is a solid-state relay — no moving contacts to weld or wear — so it's suited for high-cycle switching of resistive or lightly inductive loads in a control panel. The 22.5 mm width means it fits standard DIN-rail enclosures without crowding adjacent devices. RoHS compliance is confirmed since 15-01-24, and the part carries a REACH Article 33 declaration for lead (CAS 7439-92-1) above 0.1% w/w. This matters for EU regulatory filings and end-of-life reporting on the equipment it goes into. ## Integration notes The 22.5 mm width and screw terminals are straightforward for panel wiring — strip 8-10 mm, torque to the terminal rating. The 24 V DC control side is common for PLC digital outputs; verify the sink/source polarity against your controller's output card.","metaTitle":"Siemens 3RF3125-1AA02 SIRIUS 3RF31 Solid-State Relay, 25 A","metaDescription":"Siemens 3RF3125-1AA02 SIRIUS 3RF31 solid-state relay, 1-pole, 22.5 mm, 25 A, 24-230 V / 24 V DC screw terminal.
