The 3RH1431-1AR60 drops into the same Size S00 footprint and uses the same screw/snap-on mounting, so a panel designed for the 3RH2440-1AP00 can accept the 3RH1431-1AR60 without rewiring if the contact configuration matches the circuit. Verify the NO/NC count before swapping."},{"question":"What compliance documentation does Siemens provide for 3RH1431-1AR60?","answer":"The part carries RoHS compliance with a substance prohibition date of 07/01/2006. Standard Siemens documentation includes a CE declaration and a manufacturer's declaration for REACH; UL and IEC ratings are covered in the datasheet. No specific UL file number is listed in this record, but the 6 kV surge voltage resistance and pollution degree 3 align with IEC 60947 requirements."},{"question":"Where can I buy 3RH1431-1AR60?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
