It switches loads on a 48-460 V supply and is controlled by a 4-30 V DC signal for instantaneous switching. Termination is via screw terminals. The AC-15 rating means this contactor is designed for switching electromagnetic loads — solenoids, contactor coils, and similar inductive circuits — not resistive heaters. The 12 A figure at 40 °C is the thermal current limit; expect derating at higher ambient temperatures. ## Integration notes The 3RF3320-1BA44 uses screw terminals for power and control wiring. The control input accepts 4-30 V DC, which is compatible with standard 24 V DC PLC outputs. The 48-460 V supply range covers common three-phase line voltages across global installations. Packaging dimensions are 105.00 x 27.00 x 122.00 mm, so it occupies a single 27 mm wide module on the rail — useful for panel layout planning. RoHS compliant since 15-01-24.","metaTitle":"Siemens 3RF3320-1BA44 SIRIUS 3RF33 solid-state contactor, 1-","metaDescription":"Siemens SIRIUS 3RF3320-1BA44 solid-state contactor, 1-pole, AC-15 12 A at 40 °C, 48-460 V supply, 4-30 V DC control, screw terminals.
