The 48-460 V supply range covers common three-phase line voltages across global installations, while the 4-30 V DC control input accepts standard 24 V DC PLC outputs without an interposing relay. The ring cable lug connection suits permanent wiring in control panels where vibration resistance matters. The AC-1 30 A rating at 40 °C defines the continuous resistive load it can switch without derating. For motor or inductive loads, AC-3/AC-4 ratings would be lower — this part is sized for heater banks, lighting, or transformer primaries, not direct motor starting. The 4-30 V DC control range means it triggers reliably from a 24 V DC PLC output with margin for voltage drop along the cable run. No auxiliary supply needed beyond the control signal. Mounts on standard DIN rail. The ring cable lug connection requires a ring terminal on each power wire — verify lug size matches the terminal stud before terminating. Control wiring is polarity-sensitive for the DC input; observe the marked + and - terminals. The 105 x 27 x 122 mm footprint fits alongside SIRIUS 3RF32 and 3RF34 siblings in multi-contactor arrays.","metaTitle":"Siemens 3RF3330-3AA44 SIRIUS 3RF33 Solid-State Contactor, 30","metaDescription":"Siemens 3RF3330-3AA44 solid-state contactor, 1-pole, AC-1 rated 30 A at 40 °C, 48-460 V supply, 4-30 V DC control.
