AC-1 covers resistive or slightly inductive loads — heaters, ovens, lighting banks — where the current waveform stays near sinusoidal and inrush is minimal. That 50 A figure is the continuous current the triac pair can carry without exceeding the junction temperature limit, so it sets the steady-state capacity for a resistive circuit. For motor or transformer loads (AC-3 or AC-4), the switching current is lower; the datasheet's derating curve governs that choice. ## Control voltage and termination The control circuit accepts a dual-range supply: 24-230 V DC or 110-230 V AC. That covers both 24 VDC control panels and standard 120/230 VAC line-voltage pilot circuits without an interposing relay. Termination is via screw terminals, which suits panel builds where ring-tongue or fork crimps are preferred over spring-clamp. The packaging dimensions — 105 x 50 x 125 mm — give the DIN-rail footprint for a 1-pole block; verify clearance for the screw-terminal wiring gutters during panel layout.","metaTitle":"Siemens 3RF3350-1AA22 SIRIUS 3RF33 Solid-State Contactor, 50","metaDescription":"Siemens 3RF3350-1AA22 solid-state contactor, 1-pole, 50 A AC-1 at 40 °C, 24-230 V / 110-230 V AC control, screw terminals.
