AC-15 is the switching category for electromagnetic loads — solenoids, contactor coils, clutches — where the inrush can be several times the holding current. The 25 A rating means this contactor handles those inrush peaks without welding or contact degradation, which is the whole point of going solid-state over a conventional electromechanical contactor in a coil-heavy control circuit. ## Control and load voltage range The load circuit accepts 48-460 V AC. The control input is 4-30 V DC, compatible with 24 V industrial DC supplies. Instantaneous switching responds within milliseconds of the control signal. This part carries an active lifecycle status, meaning it is current-production and available through standard Siemens distribution channels. For a maintenance-spares purchaser, this is the straightforward case: no last-time-buy pressure, no need to hunt surplus. If your BOM requires full RoHS exemption documentation or REACH Article 33 communication, the compliance records are on file. ## Integration notes Screw terminals simplify panel wiring — no special crimp tooling needed. The packaging dimensions (105 x 50 x 125 mm) mean it fits a standard 22.5 mm or wider DIN-rail footprint with room for adjacent devices. For a panel-builder or wireman, the spring-cage alternative is common in the 3RF3 family, but this variant is screw-clamp; verify your terminal block preference matches. The single-pole configuration suits single-phase loads or DC switching where only one line needs breaking.","metaTitle":"Siemens 3RF3350-1BA44 SIRIUS 3RF33 Solid-State Contactor, 25","metaDescription":"Active-production Siemens SIRIUS 3RF3350-1BA44 solid-state contactor, 1-pole, 25 A AC-15 at 40 °C, 48-460 V load, 4-30 V DC control.
