Siemens Sirius 3RF2350-1AA04 is a DIN-rail mounted, single-channel solid-state contactor (SIRIUS 3RF2) rated for 1-phase AC loads up to 50 A at 40°C ambient. It accepts a 24 V DC control signal and switches loads over a 48–460 V AC range, employing zero-cross switching to minimize electrical stress and audible noise. Typical applications include heating elements and valves where quiet, wear-free switching is advantageous. Key specifications include a 24 V DC coil, 48–460 V AC load voltage range, 50 A rated load current (AC-1) at 40°C, DIN-rail mounting, and screw-terminal connections for input and load terminals.
