The Siemens 3RF3350-3AA04 is a SIRIUS 3RF33 solid-state contactor, 1-pole, rated AC-1 50 A at 40 °C with a supply voltage range of 48-460 V and a 24 V DC control input. It uses ring cable lug connections. The 1-pole configuration switches one line, so for single-phase loads or one leg of a three-phase circuit, it fits directly.
RoHS compliance is documented since 15-01-24, and the REACH Article 33 duty-to-inform is triggered by lead (CAS-No. 7439-92-1) above 0.1% w/w — a standard declaration for certain alloys in the terminal hardware. No special export controls apply (AL: N / ECCN: 9N9999).
Integration notes
The 24 V DC control coil is standard for PLC-driven panels — no separate control transformer needed if your cabinet already runs 24 VDC. The ring cable lug connection means you terminate with ring terminals, not fork or pin types; verify your lug size matches the terminal stud before wiring. The 1-pole body leaves adjacent slots free for additional poles or auxiliary blocks in multi-phase builds.
