AC-1 covers resistive or lightly inductive loads — heaters, ovens, lighting banks — where inrush is minimal and the current waveform stays near sinusoidal. That 50 A figure is the continuous current the semiconductor junction can carry at 40 °C ambient; push the ambient higher and the current must be derated, though the datasheet curve is the reference for that. The load voltage range spans 48 to 460 V AC, and the control circuit accepts 110 to 230 V AC — a standard industrial control voltage that lets it drop straight into a panel fed from a 120 V or 230 V control transformer. Termination is via screw terminals, which suits panel builders who prefer a positive clamp over spring cages for higher-current solid-state paths. The 3RF3350-1AA24 is a DIN-rail-mount solid-state contactor, sized for a standard enclosure cutout. Its 105 x 50 x 125 mm package (L x W x H) means it occupies roughly the same footprint as a 3-pole electromechanical contactor in the 50 A class, but without the coil hum and with zero contact wear. For a panel builder, that translates to no arc-chamber clearance needed and no auxiliary contact wear to budget for in high-cycling resistive loads.","metaTitle":"Siemens 3RF3350-1AA24 SIRIUS 3RF33 Solid-State Contactor, 50","metaDescription":"Siemens 3RF3350-1AA24 SIRIUS 3RF33 1-pole solid-state contactor, 50 A AC-1 at 40 °C, 48-460 V load, 110-230 V AC control.
