30 kW AC-3 at 400 V — motor switching ceiling
The 3RT5044-1AD20: The 24 V AC coil (50/60 Hz) keeps the control circuit at a safe extra-low voltage, common in PLC-driven panels where the I/O rack supplies 24 VAC. Size S3 frame with screw terminals — the terminal layout matches the SIRIUS S3 footprint, so a swap-in replacement on an existing DIN-rail assembly is straightforward without re-drilling the subplate.
Current lifecycle and compliance check
RoHS compliance date is 05/01/2012, meaning the contactor meets the EU RoHS substance restrictions effective from that date.
