The Siemens 3RF3380-3BA04 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for AC-15 duty at 27.5 A at 40 °C. That AC-15 rating means it's designed for switching electromagnetic loads — contactors, solenoid valves, brakes — where the inrush current can be several times the holding current. The solid-state switching handles those repetitive inrushes without contact wear, so it's a fit for high-cycle applications like conveyor divert gates or packaging-line actuators. Load voltage range is 48-460 V AC, controlled by a 24 V DC input for instantaneous switching. Termination is via ring cable terminal, which is a screw-clamp style that accepts ring lugs — common in North American panel builds where ring terminals are preferred over ferrules for high-vibration environments.
RoHS compliance is confirmed since 15-01-24, and REACH Article 33 disclosure notes lead (CAS 7439-92-1) above 0.1% w/w in the product. This is a standard declaration for certain electronic components — it doesn't restrict use in industrial equipment but may require documentation for end-of-life recycling programs.
Integration notes
The 3RF33 series mounts on a DIN rail (standard 35 mm EN 60715) inside a control panel. The ring cable terminal accepts conductors sized for the 27.5 A rating — typically 4-6 mm² for the power circuit. The 24 V DC control input is polarity-sensitive; verify the DC supply orientation before commissioning. No auxiliary contacts are integrated in this base variant, so if feedback to the PLC is needed, plan for an external auxiliary contact block or a separate monitoring relay.
