AC-1 covers resistive and slightly inductive loads — heaters, ovens, lighting banks — where the current waveform stays near sinusoidal and inrush is minimal. For motor loads (AC-3 duty), the same contactor derates significantly; the 40 A figure is not the motor-switching current. ## Control voltage and termination The control input accepts 4-30 V DC, covering 5 V logic, 12 V PLC outputs, and 24 V industrial supplies without a separate interface relay. Screw terminals on both power and control sides — no spring-cage tool needed, which matches the preference on panels where the wireman carries a Pozidriv, not a screwdriver with a slim blade. The 48-600 V operating range on the power circuit means it works across 48 V, 120 V, 208 V, 240 V, 277 V, 400 V, and 480 V nominal systems without a voltage-select jumper.","metaTitle":"Siemens 3RF3340-1AA45 SIRIUS 3RF33 Solid-State Contactor, 40","metaDescription":"Siemens 3RF3340-1AA45 SIRIUS 3RF33 solid-state contactor, 1-pole, 40 A AC-1 at 40 °C, 48-600 V, 4-30 V DC screw terminal.
