That 50 A figure is the maximum steady-state current the SSR can carry when properly mounted on an adequate heatsink — the datasheet explicitly states it requires mounting on available cooling surfaces, so panel integration must account for thermal management. Control voltage is 24-230 V AC/DC, with the logic input accepting 24 V DC via spring-loaded terminals. This SSR is designed for chassis or panel mounting onto a heatsink — it is not a stand-alone DIN-rail module with integral cooling. The 22.5 mm body width matches the SIRIUS 3RF3 series, so it shares the same drill pattern and terminal layout as other 1-pole 3RF3 units. The packaging dimensions (104 x 44 x 48 mm) give the envelope for panel layout planning.","metaTitle":"Siemens 3RF3150-2AA02 SIRIUS 3RF31 SSR, 50 A, 22.5 mm","metaDescription":"Siemens 3RF3150-2AA02 SIRIUS 3RF31 solid-state relay, 1-pole 50 A, 24-230 V / 24 V DC control, spring-loaded terminals, requires external heatsink.
